Thanks for the incredibly prompt reply.
That makes sense, except that to the best of my knowledge the year zero
is not valid in either the Julian or Gregorian calendars.
I had assumed that strtotime would return FALSE for invalid dates. On
my 32 bit Ubuntu system, this appears to the case.
strtotime("2011-01-32") returns FALSE, as opposed to returning the
timestamp for "2011-02-01".
An in depth reading of the documentation did not clarify how strtotime()
should be expected to handle invalid date strings.

This is expected. On 64-bit systems the date range supported is much
larger than
on 32-bit systems.

strtotime() produces different output on 32 and 64 bit systems running
PHP 5.3.
This affects the "zero date" ("0000-00-00 00:00:00") as well as dates
outside the
traditional 32 date range.
strtotime("0000-00-00 00:00:00") returns FALSE on a 32 bit system.
strtotime("0000-00-00 00:00:00") returns -62169955200 on a 64 bit
system.
Test script:
---------------
<?php
var_export(strtotime("0000-00-00 00:00:00"));
?>
Expected result:
----------------
On 64 bit systems, I would expect strtotime("0000-00-00 00:00:00") to
return
FALSE as it does on 32 bit systems.
Actual result:
--------------
On 64 bit systems, strtotime("0000-00-00 00:00:00") returns
-62169955200.
