@kalmly,

Please read GOTD's note carefully: "Single License (1 PC) with 1 Year upgrades is included in this version."

And then see the official page.

"Single License (1 PC) with 1 Year upgrades" is $19.99 exactly
$29.99 is "Single License (1 PC) with Lifetime Upgrades".

Hope it helps.

TSS

TSS, Ohhhh, got it. Thanks.

@Kate ,

OK, we will ask GOTD to do that.

Thank you.

TSS

@Gary Smith,

Please see its online help (Press ).

The "Algorithm For [Years] And [Months]" segment.

Hope it helps.

TSS

TSS, The online Help section pertaining to the Algorithm for Years and Months is pretty simplistic:
Algorithm For [Years] And [Months]

[Years] = [Seconds] / 3600 / 24 / 365.25
In above expression, 365.25 = the average days in 4 years (3 non-leap years + a leap year) = (365 * 3 + 366) / 4.

[Months] = [Seconds] / 3600 / 24 / 30.4375
In above expression, 30.4375 = the average days in 48 months (the months of (3 non-leap years + a leap year)) = (365 * 3 + 366) / 48.

Sure, no problem with the years and months resultant values ...

But what does that have to do with the hours being off and the minutes being off in the example I asked about? The two times I used both are on the half hour (30 minutes after the hour). From one 30 minutes past the hour to any other 30 minutes past the hour cannot be anything other than full hours. The minutes difference would always be zero (obviously, we are calculating within the same timezone and same DST). Even though there are other programs that calculate this difference accurately, and the free online timeanddate.com difference calculator calculates this difference accurately, no one really needs to test it out to see how this program's answer of 30 minutes is correct. Since both date/times use the same minutes value (30), the resultant minutes has to be zero. No explanation of how years or months are calculated from the seconds can explain away the resultant minutes being off by 30 minutes. Also, the hours should be correct as well. Clearly there is 4 hours difference between 15 and 19. How this program comes up with 17 hours difference is bizarre.

In the example I listed, if the end date is changed to August 9, the number of minutes is zero and the number of hours is 4, both correct, but if the end date is changed to one day later (August 10th), the result hours jumps to 17 hours and the minutes changes to 30 minutes.

Is there something special about what will happen between August 9th and August 10th? Is this program predicting an asteroid hit? ... or anything that might throw off how we calculate time afterwards? I am really curious.

This application's website online (http://www.trisunsoft.com/advanced-date-time-calculator/) example to show the difference feature uses these two times:
July 9, 1975 12:44:38 and September 7, 2012 18:09:12 but the result shows the number of hours different to be 2 hours and the minutes as 24 minutes (the seconds result is correct by the way). The online timeanddate.com difference calculations disagree with the result this program shows. Can you point me to any other program that agrees with this program's results?

Press "F1" (GOTD cannot display angle brackets, so above sentence is not completed).

@Gary Smith,

[Months] = [Seconds] / 3600 / 24 / 30.4375
In above expression, 30.4375 = the average days in 48 months (the months of (3 non-leap years + a leap year)) = (365 * 3 + 366) / 48.

So, how many days in "1 Month" (a common concept) do you think?
28 days?
29 days?
30 days?
31 days?

Our algorithm considered the average for all months in Christian era.

Not so simple as you think.

Hope this helps.

TSS

TSS,

THE PROGRAM HAS A BUG! HERE IS HOW TO SEE IT.

The difference tab CALCULATES A WRONG RESULT for hours and minutes when the span goes over a month.

When the program starts, the difference panel shows the current date and time, in the From and To fields. Leave the "To" hours, minutes, and seconds section as it is, but click the down arrow on the "To" date, then advance one month into the future. Select the exact same day number as the "From" value.

Since the time values are the same for the "From" and "To" fields, the result should show nothing for the hours, minutes, and seconds since they are zero ... but instead, it shows a non-zero value for number of hours and minutes. I get 13 hours and 30 minutes. How is that possible when both times are the same? No matter how you calculate years and months, it should not affect the hours and minutes result. Both should be zero in this example.

Now, for the "To" field, pick the day before the previous value and the results will now be correct.

The problem exists as soon as the "To" field goes over a month.

Since most users do not have anything to compare to, they have not questioned the results.



>So, how many days in "1 Month" (a common concept) do you think?
>28 days?
>29 days?
>30 days?
>31 days?

>Our algorithm considered the average for all months in Christian era.

>Not so simple as you think.
Sorry, but it is not difficult either.

Many years ago, I wrote code to do the same calculations, and it calculates accurately, plus the final results agree with the difference calculations on timeanddate.com. I also developed a version that accurately counts the days in the months between two dates based on the actual number of days in each month between the two dates, regardless if the month has 28, 29, 30, or 31 days; each month in between may be different but should be accounted for. For any starting month, there is a number of days remaining until the end of the month, and there is a number of days into the "to" month. Add all of these up produces a total days result that is correct, and not based on any average. Using the in between values as months, leaves the remaining days portion. The number of days until the end of the starting month added to the number of days into the final month, may total more than our longest month of 31 days, so most agree that an average number of days should be subtracted to increase the number of months results by one month, and to have a number of days remaining less than a common month. Due to the complexities of this method (it has to be explained to the user), most will agree that there is no real issue with using an average to calculate years and months. That is also why I have no issue with how this program calculates years and months ... that is not where the program has a problem.

As I already stated, I have no problem with the years and months calculations, but please acknowledge that the hours and minutes results are wrong in the case I demonstrated above.

@doseas,

Sorry, I cannot find out where is the "same thing".
And SMPTE (like SMTP) Calculator, too odd name. Why not named to POP3 Calculator?

Hope it helps.

TSS

TSS,

SMPTE = "Society of Motion Picture and Television Engineers".

A SMPTE calculator is used in the film and audio industry for calculating dates & times.

I've been using a number of free programs for the PC, Amiga & Android all the way back to 1985, when I started in the industry.

Techie Bear, How about a real calendar or electronic screen calendar and by the way nobody follows those dates on the bottle, people come back for re-fill when the bottle is down to one pill or empty.

That is the calendar most of us use, visual needs when the bottle is empty. How about when people use more pills than prescribed doses, how about when people spill the bottle and lose many pills, they would not read the bottle, they will show up at your window with an empty bottle days before the date written on the bottle.

Instead of a date, please just write, re-fill as many times as needed.

kindt, I follow the dates on the bottles religiously, so I have to say you are wrong in your statement..sorry. We know the Pharmacy knows exactly when your due to refill, and maybe, (for persons like myself that just had serious spinal surgeries - I had 3 spinal surgeries in 5 weeks over the 2015 Holiday season), We don't go by how many pills are left in the bottle, (Because maybe a day or 2 or 3 we had to "double-Up" on our meds to to severe pain). Then, we have lost count, and a program like this would be VERY VERY BENEFICIAL to me and possible others like me. I will be sharing this program download to my friends today, before the time runs out.

kindt, Please read carefully the statement before commenting on it. Techie Bear clearly stated that it was used for several dozen prescriptions for multiple people (long term care facility). There, pills are distributed by staff, who cannot wait until the bottle is empty to apply for a refill.

It is also handy for calculating due dates on GICs, -- I don't have to take my shoes off to count past 10.

J R, It probably did not install. When this happens to me I temporarily disable the firewall and antivirus and then it will install.

J R, So you unzipped them, then went to that unzipped folder and installed from there?

J R, Remember unzipping is NOT installing! If you only unzip them then you haven't done a thing yet. Are you sandboxing them by any chance? If so, change your settings so they install to the target drive and not a virtual!

@ papin

Maybe you should take a look at "Calendar Magic" which you will find at this address :

"http://www.stokepoges.plus.com/calendar.htm"

I don't mean that you will find for sure what you are looking for but if there is a software that could do what you want, "Calendar Magic" could be one of those.

papin,
Tried to write a program that told the time in three different zones that accounted for clock changes, I got tied in knots.

There is a huge bug in NT when there are clock changes; it makes it almost impossible to use time when protecting your program.

As a developer I hate to use the registry and took three months writing the protection code for my programs.
I used a file with information in it that was encrypted with the time and date of the file, in an attempt to stop hackers. Works great until a time change and even though the time looked the same when examined the encryption and decryption failed.

This also happened when I was a programmer, it was an expensive £7000 program that used the time and date in its protection. Every time there was a time change our help line would be inundated with calls from NT users when the program wouldn't open.

As you say the date and time in Windows can become very complex.

Sputnik,

Thanks for your advice, but no thanks. It seems you didn't understand the goal of my post. I do not need a calendar software.

To make it clear, I was pointing out the drawbacks of this GOTD, which does not take into account TZ and DST to compute dates. And one serious limitation, it cannot convert dates from one calendar to another calendar, even for a limited set of calendars.

For all date & time calculations (and more, of course) I do the programming myself with python.

This said, Calendar Magic looks nice and apparently does convert dates between calendars.

@ papin

I know this software since a couple of years but I never used it. I just remembered that it was able to perform calculations on dates but not exactly which. It is more than just a regular calendar. This is the reason I suggested this software to you. Sorry that you didn't find what you are looking for.

Tata,

Many systems cannot deal correctly with a date-time object because there is only one value to refer to : the UTC time, regardless of TZ and DST. Unfortunately, many systems try to be smart, but many fail because they either don't save time as UTC, or they don't store the TZ + DST information bits required to make the time have a meaning (not just for humans).

So, as long as you can't tell whether a time is a local time (TZ + optional DST) or not (if it's not local it must be UTC), you're in trouble. Hence your problems.

For a time to have a meaning not only for humans, it must store TZ and DST information bits.

When checking a time, you must take into account the validity of the DST, because DST is a very political issue. To a lesser extent, the TZ too. Changes in TZ although extremely rare may happen as well, see www.timeanddate.com/news/time/venezuela-change-timezone.html for a recent example.

For those who don't know, the NT bug comes from the Microsoft's way of doing things. Instead of displaying the file time according to the local settings while keeping the file time t its real value in UTC, it modifies it according to the DST if set (support.microsoft.com/en-us/kb/129574). Still, the file's metadata does not include TZ nor DST information. This is more than a bug. It is a failure within the OS. Informative reading: funduc.com/text/tzadjust.htm.

papin,
Thank you so much for the information regarding the NT bug.
Wish I'd been aware of it before I spent three months writing my program protection system.
One I would really proud of as it would of taken a first rate hacker to get past it, had a nice bit when SoftIce was detected.
The bug was a real nuisance as it didn't show up when the program was debugged, when Microsoft mess up they do it in style!
Doing it in Skype in a big way.

@Louis,

That's obvious: "Single License (1 PC) with 1 Year upgrades is included in this version." - after 1 year, you cannot upgrade your copy (version).

TSS, Thank you for replying, however, the way you phrased it in the description, makes it open to more than one interpretation, so it's not obvious : "Single License (1 PC) with 1 Year upgrades".

My question wasn't answered :

Does that imply the licence is only valid for 1 year, along with the 1 year of upgrades, OR, does it mean the licence is permanent, but with only 1 year of upgrades.

I wouldn't like to install this kind of mission critical software based on a probability guess, only to find my data inaccessible in the middle of a semester.

@Heather,

The setup.exe is provided by GOTD, you can ask them for support.

But it's easy to solve:

Download ADTC from its official page, and then input the key.

TSS

Heather, The shame is that you are not getting that there is something unique about your OS configuration that is causing the failures. Many, many other GAOTD users are succeeding with the installations. Over the last few weeks I myself have found many of the giveaways particularly useful on one or more of my three household Windows 10 64 bit systems. Each download has installed flawlessly. My particular security system includes Windows firewall and Windows Defender with default settings plus Malewarebytes pro. I have not had to disable anything for successful installations. I am sure if share the details of your setup with the regulars here you can get some troubleshooting assistance to find out what is unique about your PC that is causing problems that the majority of other down loaders don't run into.

@ABMM,

We don't think it is a bug: a user can only install a program for himself/herself, he/she can not decide for others.

This is a special design for our most products - do not install for other peoples!

About the permission, you should ask your system administrator to obtain.

Hope it helps.

TSS

TK,
When I write my programs in Delphi I have no input as to who can install it.
Surely it is the installer causing the problems and not the actual program itself.
Would really appreciate your comments on this as I know you have a great depth of knowledge from the comment you have made over the years

TK, All I can say, that this is first time that I have this kind of problem, and I have used restricted/normal user account my daily use from XP to W10. So, there is something definitely wrong with this program.

Of course, system settings and configurations are differences, but as I said, no such problems have been other programs. So it worked with you, but not on my system.

@Andy,

@TriSun: now the promo for lifetime licence for 3 PC's is right for me! Please update on regular basis. Make GUI a little more modern, remove the register-icon for registrated lifetime users, make it better and better.... improve! :)

And please, also offer the same lifetime promo for Date Time Counter & Easy Work Time Calculator. But remember: update the programs regulary - with new stuff and looks of interface ;)

Thanks everyone for the read and a happy Sunday with TriSun-software :)))
Big kiss for Tata!

@Kate ,

Thank you.

For your requests:
1. Interface - for Windows users, there are two choice: 3D interface (traditional) - from Win95~Win7, Metro interface - from Win8~Win10, some users like the traditional style, and some else like Metro. This is hard to meet all people. But we have some considering in this, in the future version.

2. Remove register icon - cannot, please consider an user want to upgrade her/his license from Personal License (3 PCs) to Home License (10 PCs), then, how to register the license?

3. For Date Time Counter & Easy Work Time Calculator - have some upgrade plans, and once the new version is released, we will ask GOTD to make the giveaway for everyone.

Thank you again.
TSS

You can do the same thing with excel.

I tried it wit Excel 2007 in different ways, but was not able to get a correct result.

Ghost Writer,
Just had a look at Excel 2002 daytime functions and frankly it would be streaming difficult or not possible at all to do all of the functions available in today's download.

Kate ,
Thank you, the big is gratefully accepted.
Better than the miserable load of twits who mark me down whatever I write.
Appear to be incapable of comments and their limits is pressing the no button.

@Ghost Writer,

Thank you for you time and comment.

Since Office support VBA (can do programming), for the VB programmer's, Excel can do anything.

But for the normal Windows users, they still need the software, that's why there are hundreds of millions software in world, rather than Windows OS + MS Excel.

Hope this helps.
