Summary: Inconsistent return values for strtotime('0000-00-00')
Status: Bogus
Type: Bug
Package: Date/time related
Operating System: *
PHP Version: 5.*, 6CVS (2009-04-30)
New Comment:
ahar...@php.net: Any date with month=zero or day=zero is invalid,
regardless of
the year value. '0000-00-00' is not a date and has no corresponding unix
timestamp.

This isn't a bug. The year 0 is well within the range of a 64-bit UNIX
timestamp, strtotime's semantics for invalid values (such as
defining the month and day as 0) are well established at this point,
and I see little value in special casing 0000-00-00 and plenty of
possible WTFs down the line if it's done.

We are getting this same problem, but only on 64 bit platforms. I've
tested on a
few different machines, all 64 bit machines return int(-62169955200). 32
bit
machines return bool(false) as expected. This happens on 5.2.x and
5.3.x.

I've reproduced this on CentOS with kernel 2.6.9-55.ELsmp using php
version:
PHP 5.2.8 (cli) (built: Jan 5 2009 15:01:45)
and the 5.2.8 apache module.
And I think it should go back to returning bool(false).

i was wrong with the expected results. a year of 0000 is reasonable but
neither month = 00 nor day of of the month = 00 are possible, so the
strtotime('0000-00-00') should return bool(false)

Description:
------------
strtotime('0000-00-00') returns int(-62169955200) in a script run by
apache web server and bool(false) when run by the command line.
Reproduce code:
---------------
<?php
var_dump(strtotime('0000-00-00'));
?>
this script outputs int(-62169955200) to the web browser when run as a
web page and bool(false) when run on the command line.
Expected result:
----------------
i would expect the same result from running the function in the two
contexts.
regarding which result strtotime('0000-00-00') should return, i don't
know. both answers seem reasonable to me. it would help if php
documentation would specify the range of dates and unix timestamps that
date and time functions can handle.
Actual result:
--------------
int(-62169955200) in the web page
bool(false) in the command line
