I forgot to set the date/time on my camera when I went overseas so I'm hoping that this program will calculate the time and date that I took certain photos overseas by using the time stamp on the photos and calculate the time zone difference between my country and the country I visited.

Good Question. That sounds like reasonable need to calculate a time difference for, but there is an easier solution than Advanced Date Time Calculator. Do a search for Rellik EXIF Date Changer. It was made to solve this very problem. They have two editions of the software. One is free, and one paid. The free on will solve your current problem.

If your camera has very good clock, it should be either right on time or very close. You can take a photo of the current time using a very accurate source (atomic clock), then you see just how far it has drifted. You can sync your PC clock with an atomic time source and take a photo of the time displayed on screen to do the same thing.

If you have made changes to your camera clock's time, it will not affect photos you have already taken. All you need to so is calculate the difference. EXIF Date Changer can handle that for you. Even if you do not have it, if you used another camera or a SmartPhone especially, that image can provide details of the local time where you took your other photos. You can always use timeanddate.com to calculate accurate time differences.

I installed the program and tested its “Differences” functionality but got some strange results:-

From – 13 September 2017 00:00:00
To – 13 September 2018 00:00:00

Difference (Integrated) ==> “11 months 4 weeks 2 days 4 hours 30 minutes”

Uninstalling program!

JonK, this software does have calculation flaws.
The first tab "Date & Time" doesn't even work properly. I assume this one is to calculate the difference between a date in the past or future to present day. Well, it doesn't work at all. Tri Sun, I think you should correct the errors in your software, certainly the version giveaway today doesn't work 100% and then list it again. The software does have some merit, even though it may only be for entertainment.

JonK, Don't worry I don't understand that either same result from an old giveaway of version 4.0 I have of this that I never used before... decided to try a similar test of the Date & Time calculator and
From
14 September 2018 01:02:09
and selected ADD 1.0 years and the resultant date and time became:
14 September 2019 07:02:09
so seems a year is six hours longer than a calender year....
Which it is IF you use 1.0 year = 365.25 days which is what this DUMB program is doing! I should factor in leap years into the calculation as we don't live by 365.25 day years but 365 days for 3 years then 366 days for one year and so on.
While tehnically it may be correct, in real terms it is completely wrong and renders itself unusable and just plain weird in its calculations.

Thanks, TSS.

But if the program can’t produce the simple answer of “1 Year 1 Day” from 13 September 2017 to 13 September 2018, I think you should rethink the correctness of the Algorithm used.

After all, we can’t tell people that, from 13 September 2017 to 13 September 2018, there is only 11 months plus something, that is, less than 1 year, can we?

Reply   |   Comment by JonK  –  7 days ago  –  Did you find this comment useful? yes | no (0)

JonK, Incorrect

To - September 13, 2018 00:00:00 is not possible. It is:
To - September 13, 2018 23:59:59 and then comes September 14, 00: 00: 00
Then: September 14, 00: 00: 01

JonK,

Thanks for your suggestion.

In fact, we always know this problem. But we think there may nobody want to calculate the difference that just one year, just like we will not use MS Calculator program to calculate 1 + 1 = 2.

So, we keep current algorithm until there is a better way to process the "just n year(s)" concept.

Hope this helps.

Thadeus Harris,

Thanks! You are right. I slipped over on the 00:00:00. The program should have been smart enough to reject the entry.

But the HH:MM:SS is placed there in the program by default and its value is included in the calculation.

What do you think we should put in the “HH:MM:SS” when we simply want to show the date of 13 Sep only?

Reply   |   Comment by JonK  –  7 days ago  –  Did you find this comment useful? yes | no (0)

JonK,

It isn't just one year that calculates wrong, it starts for one day after a month. It is easy to see. The program starts on the Difference tab with the start and end date and times the same. Change the To date to exactly one month ahead (same date number) leaving the times the same. It works. Now change to one day after that, still leaving the times the same. That starts the error.

The bug has been there from the beginning. I have tested it and verified it all along. I collect these to see if they ever change. Finally, I pointed out this same error to the developer back when it was version 4.0, and again at version 7.
https://www.giveawayoftheday.com/advanced-date-time-calculator-4-0/ (version 4)
https://www.giveawayoftheday.com/advanced-date-time-calculator-3/ (version 7)

My explanation hit the same roadblock logic we see now.

The developer attempted to explain to me why this occurs, stating "Not so simple as you think." The problem is that I have written software to do the same calculations for many years, and I never had any errors because I did it the right way, the same as all the other programs that calculate the same things. They all work, except for this one. The timeanddate.com is an easy online tool that always gets it right.

I finally decided it was best to not explain the error or how to fix it anymore. It is more interesting to see how long it will take.

Now, the developer says, "So, we keep current algorithm until there is a better way to process the "just n year(s)" concept."

Please do not tell the developer that there has been a better way for hundreds of years.

A very fast download and installation, no e-address or even real name required! I had a previous version of this. Didn't use it a lot, but when required, it does the job - and it doesn't splash your details all over the Net, not in my experience.

So . . . thank you for the update!

Bob,

Yes, Google can do some handy math operations without directing the user to any website; you get the results instantly. If I could provide you with a nice financial reward I would, if you can show us how to use Google to do this:
Given a start date and time, and an end date and time, how would I use Google to get the difference in years, months, days, hours, minutes, and seconds (without using a website Google lists)?

That is unless, you are suggesting we use some Google results website, such as timeanddate.com.

Google cannot produce accurate results, and neither can Advanced Date Calculator, so it would be nice if you can tell us how to get Google to produce the answer in the results.

Generally I don't post "bashing" comments, but this piece of software might be worth as a freebie (only). For all others there's Excel (granted, some functions are not easy to master) or timeanddate com, which allows for similar calculations, including or excluding holidays in your country of choice or timezones, for free and from any device you happen to be in front of.
Thank you GAotD, but I don't really see how the software company really earns a buck on this.

Jim B, I agree and 99% of all questions or conversions can be done by typing your question in the search bar and letting Google do it. No need for a separate app.

Reply   |   Comment by Charles Lewis  –  8 days ago  –  Did you find this comment useful? yes | no (+1)

@ Charles Lewis: Per your suggestion, on the Google search bar I entered the following question: How many seconds are there between 8 PM on January 27, 1756 and 12:55 AM on December 5, 1791? The number 1,131,425,700 didn't appear. Now what? However, today's giveaway did the math and it also displayed the difference in years-months-weeks-hours-minutes format, in years with 3 decimal places accuracy format, in months with 2 decimal places accuracy, in weeks with 1 decimal place accuracy format, in days with 1 decimal place accuracy format, in hours with 1 decimal place accuracy format, and in minutes format. Furthermore, the program also specified the day of the week for both dates. Cool that the giveaway did all that, isn't it? Finally, my 2TB Windows 10 boot drive can handle the approximate 1.62MB installed storage space today's giveaway soaks up.

Charles Lewis, MadCityObserver,

I use Google to do all sorts of math, from simple math to trigonometry calculations, logarithms, square roots, graphing, plus all sorts of conversions, but there are limits to what it can do. For example, I wanted to know how to have Google tell me how many days between 9.6.2017 and 5.6.2018. It isn't like asking Google what is 247 * 19. All of the math functions are things that the Google calculator app handles. Google does not answer questions such as these date calculations. For date calculations, you need to use an application that knows how to work with dates properly.

Take for example, the calculation needed by MadCityObserver. Google did not return the figure they received from Advanced Date Calculator of 1,131,425,700 for the time difference between 8 PM on January 27, 1756 and 12:55 AM on December 5, 1791. Advanced Date Calculator also displayed the result in years-months-weeks-hours-minutes, in addition to the seconds calculations, and with 1, 2, or 3 digits accuracy.

For convenience, Advanced Date Calculator also displays the total as 35 years 10 months 1 weeks 13 hours 55 minutes. For calculating someone's age, having a tool that can calculate down to the hours, minutes, and seconds would be handy.

But, you would never see this result from Google, no matter how much they enhance the Google Calculator to implement date functions because the answer of 35 years 10 months 1 weeks 13 hours 55 minutes is wrong!

Looking at the hours and minutes part alone shows that it has to be 4 hours, 55 minutes. From 8 PM to midnight is 4 hours, and from midnight to 12:55 AM would be just 55 minutes after midnight, a total of 4 hours 55 minutes.

You can verify these figures using the timeanddate.com website, which provides the same parts rounded down (no fractional parts), and if you like the fractional points of accuracy, you can get even more digits of accuracy (plus 6 additional fields of output) using the free and portable AdvDate developed by Paul Heinrich that was mentioned in these comments.

Advanced Date Calculation for the seconds is correct, but at minutes, it starts to be wrong due to how it calculates differences using an average for things like the number of days in a month, and days in a year, so as it stands, the results cannot be accurate.

Summary: Google cannot provide accurate date calculation results, but neither can Advanced Date Calculator.
