I know this question is very popular

Asked here
PHP: strtotime is returning false for a future date?
and here How can I work with dates before 1900 in PHP?

Could you please confirm my choices:

  1. Upgrade to a 64bit architecture

  2. Replace the strtotime calls by DateTime + DateInterval
    We can’t call DateTime->getTimestamp but we can use DateInterval to calculate the diff

Do I have any other options?
Unfortunately, I can’t pick option 2 because I am relying on ORM (Propel) + a lot of legacy code using strtotime. Refactoring this stuff + customizing the ORM generators could be more expensive than upgrading to 64bits.

If anybody could confirm or offer any other options, that would be really appreciated.

Thanks

The date format is the standard yyyy-mm-dd

PHP Version 5.3.2

    AFAIK, you are limited to these two solutions.

    You should update to 64-bit system if you can afford it, and if it solves a problem then that’s better.

    Edit: Just had to check:
    http://php.net/manual/en/function.runkit-function-redefine.php
    You could probably try and redefine strtotime() to work with dates prior to 1901.
