Is there a trac for the wordpress-i18n tools trac?
Pulling from the latest trunk and running makepot.php throws this warning. I was going to log and post a patch but wasn't sure if that should be done in core trac.
PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead in /home/lcleveland/makepot/makepot.php on line 164
