However, you do have a point. I think we even break to 32bit ints on 64
bit systems. I can check that when somebody grants me access to a 64bit
machine.

Derick, is this true even on 64bit systems? We've run into this problem
using mktime and strtotime on 5.2. For example:
mktime(0,0,0,1,1,1901) returns false
strtotime("1/1/1901") returns false
However
date('r', -2178099690) returns:
Mon, 24 Dec 1900 04:18:30 -0800
I have not figured out how to return the timestamp from a DateTime
object created with the string "1/1/1901".

It's a documentation problem. Although *internally* the new code does
support larger numbers it still can not return larger integers back to
user land. So for calling PHP functions the result can never be outside
this range.
However, the new date code which is going to make it into PHP 5.2 is
going to provide functions to deal with this correctly.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Please also tell what your system is.

Description:
------------
The documentation claims: "On systems where time_t is a 32bit signed
integer, as most common today, the valid range for year is somewhere
between 1901 and 2038, although this limitation is overcome as of PHP
5.1.0."
However, based on my testing this is not the case. mktime still returns
FALSE for dates outside of this range.
