Description
Function stdWrap.age assumes that year always consist of 365 days. It leads to wrong age calculations when measured in years. Since ver 4.2 we can use negative timestamps so we can store birthdays and then use stdWrap.age to render ages of people, but because of this bug ages are being shown incorectly.

Replace the 365 in the calcAge function with 365.2425!!!
http://en.wikipedia.org/wiki/Year#Calendar_year
This reduce the calculation mistake with very "old" calculations against 0.

The issue is very old, does this issue exists in newer versions of TYPO3 CMS (4.5 or 6.1)?

This is still unchanged in ContentObjectRenderer.php.

This doesn't solve the bug, as around birthday date the age would be rendered incorrectly, so it is still useless for displaying age of people.
For example if current year is leap year then age rendered by stdWrap.age will increase a day before than actual birthday.
So, to correctly fix that should be used PHP date time functions working with actual calendar.

This function calculates the age for given seconds, so you don't have the qualified dates for that calculation. So the function don't know when there is a leap year or leap seconds.
The calculation is enough for what it is used inside the core.
The function exists as
- TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer::calcAge
- TYPO3\CMS\Backend\Utility\BackendUtility::calcAge
To get the wanted functionality we should implement one new function with an other parameter structure and use DateTime diff. The old functions could be deprecated then.
@Ernesto would you vote for the change? If yes, where to put this one function?

Not really. The function uses date in form of UNIX timestamp not just period of time in seconds.
From TSref:
If enabled with a "1" (number, integer) the content is seen as a date (UNIX-time) and the difference from present time and the content-time is returned as one of these eight variations:
Since TYPO3 allows negative timestamps then the age function can be used to display age of people too, if not this bug.
UPDATE: I understood you now, you are talking about calcAge() function and I'm about stdWrap's age function.
In this case I think better not to use calcAge() in stdWrap's age calculation, as it is not working with dates.
The bug itself is about stdWrap's age.
Updated by Alexander Opitz about 11 years ago
So the problem is the function:
public function stdWrap_age($content = '', $conf = array()) {
$content = $this->calcAge($GLOBALS['EXEC_TIME'] - $content, $conf['age']);
return $content;
}
It only gives the seconds of difference to the real calculation function. So we should solve this with my given proposal.

- Tracker changed from Bug to Task
From #51628
A suggestion from Phillip Gampe: ... should refactor the method to use DateTime->diff(), which should be accurate, but does only exists for PHP 5.3. Thus it cannot go into 4.5. @see http://stackoverflow.com/a/3923228/1234469 I would even suggest that you turn this "bug" into a TASK and we submit this only to 6.2 with the subject "Precise date calculation for stdWrap.age". This should be covered with unit tests of course (which in this case a really simple, because we do not need mocking).

Sounds like a nice idea and using DateTime object would be the way to go. PHP 5.3 and TYPO3 6.2 fits.
A central "calcAge" method (with a better name maybe) could be placed in a new core\Utility\DateTimeUtility which could also hold GeneralUtility::convertMicrotime and GeneralUtility::milliseconds

@Ernesto
As you are assigned, do you want to do this?

I would want to, but won't have the time. I didn't assign it to myself, you did that. :)

Another problem is the rounding on some parts, so it is possible that after 1,5 years the value 2 years is shown.
