Hi everyone, I'm on a new host and while installing my SMF 2.0 RC5, I get this error!

Notice: date_default_timezone_set() [function.date-default-timezone-set]: Timezone ID 'Etc/GMT-7.5' is invalid in /home/mnmltsg/public_html/install.php on line 270

Can any please let me know how to fix it?

Try re-uploading the SMF files and try the install again, if that doesn't work have a look at http://www.simplemachines.org/community/index.php?topic=187292.0
