## #7189 — Jonathan Hernandez — 2004-01-19T19:20:58+00:00

Hello,

I have a problem with mktime, when I try to run this:

<?php
$date = getdate(mktime(12, 0, 0, 1, 1 ,1959));
echo $date[0]."
".$date['mday']."-".$date['mon']."-".$date['year']."<br/>";
$date = getdate(-347090400);
echo $date[0]."
".$date['mday']."-".$date['mon']."-".$date['year']."<br/>";
?>

Output:
-62 31-12-1969
-347090400 1-1-1959

I compile php5.0b3 on Fedora(gcc 3.3.2/ kernel 2.4.22), if I try to run
it on Debian (gcc 2.95.4 / kernel 2.6.0) it works fine, 

Output:
-347090400 1-1-1959
-347090400 1-1-1959


Both php are compiled with the same ./configure line...


Any idea about this?



Thanks in advance,

Jonathan

Your libc doesn't support negative time_t values.

Well, I see that is a normal behavior of libc/mktime (it returns -1 if
an error was detected), I see others have the same problem and
implements their own php/mktime function (see the first comment on
http://www.php.net/mktime)... I wonder if it can be implemented directly
on the php function...
