I receive such message, but I believe it’s working:

Warning: strtotime(): 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 the timezone ‘UTC’ for now, but please set date.timezone to select your timezone. in /Applications/Logs/fixskew.php on line 29

any ideas?

Thats just a PHP warning - it will still work just fine. There is only a problem if you have date time strings from different time zones.

If you want to get rid of the warning edit your php.ini file and set your timezone
