php why new DateTime ('now') returns 1970 after 2038

Question

I decided to check the end of the unix epoch, so I change the date more than 2038 in my calendar. I surprized that the:

$now = new DateTime('now');    echo $now->format('Y-m-d');

RETURNS 1970-01-01 !

$now = new DateTime();

returns same and php 5.4 returns same. However:

$now = new DateTime('9000-10-01');

returns 9000-01-01. How to get current date after 2038 using DateTime?

My OS: winxp x32 and php 5.3/5.4 x86.

Move to a 64-bit system and 5.2+ and you are good to go beyond 2038 — Hanky Panky, Dec 10 '14 at 17:56

"How to get current date after 2038 using DateTime?"

I'd consider using a fully 64 bit stack and OS. And by the way, the unix timestamp convention is not used only in unix/linux.

See php time function as a good example. This function cannot give a result for dates after 2038, if you use only 32 bits integers.

dotpush

You are right. php x64 doesn't have such problems. It's problem only in php x86 (even in Windows 7 x64). – user3551026 Dec 11 '14 at 09:31
