i'm not sure it's problem of cygwin or php of corse, as cygwin is not
supported by php.
same problem in php4, but there's no warning with date() strtodate().
putenv("TZ=GMT"); helps, but not putenv("TZ"); in php script before
date()
<?php
echo "<pre>";
echo "\nwith putenv TZ:";
putenv("TZ");
echo date("H");
echo "\nwith putenv TZ=GMT:";
putenv("TZ=GMT");
echo date("H");
echo "\nwith putenv TZ=GMT-8:";
putenv("TZ=GMT-8");
echo date("H");
echo "\nwith putenv TZ= -8:"; // 3 spaces before +
putenv("TZ= -8");
echo date("H");
?>
====================
with putenv TZ:
Warning: date(): Cannot find any timezone setting in
/cygdrive/d/www/test/test.php on line 5
with putenv TZ=GMT:10
with putenv TZ=GMT-8:
Warning: date(): Cannot find any timezone setting in
/cygdrive/d/www/test/test.php on line 11
with putenv TZ= -8:
Warning: date(): Cannot find any timezone setting in
/cygdrive/d/www/test/test.php on line 14
====================
i have no problem with simple test program but no idea on how to go on
to trace php
int main() {}
$ gdb ./a.exe
(gdb) br main

Apparently the TV environment variable *is* set... you need to try to
figure out where this happens. If it's not set by yourself, you should
try to figure out why cygwin does this - that's obviously not PHP's
problem.
