How to calculate dates > 1-19-2038 ?

[DavidRock]

Hello,
I need to add 65 years to a birth date to compute the retirement date for an individual. I need to take leap years into account and was using the following example which fails when the result is > 1-19-2038:

$retire = strtotime("1974-01-06 + 65 years"

Is there a workaround I can use that takes leap years into account?

Thanks for your help,
David

Have you searched for a PHP extention willl do long dates ?, if one doesn't exist I would the calculations are straight forward and could be implemented quite easily.

Try the PEAR Date class. It doesn't user UCE time ticks.

Thanks for the responses. I installed the PEAR Date and Calendar classes and looked through them but don't see a function to calculate a future date that's years in the future. Is it there and I'm just missing it?

Thanks for pointing me to PEAR btw, looks like lots of good stuff there.

Thanks

How are you adding periods to the date? If you're adding whole years, pull the date string apart, add to the years, and put the string back together.

The version of the Date PEAR class I downloaded from pear.php.net included functions named addSeconds and addSpan.

Thank you sleipnir214, those functions sound like exactly what I need.
