I've managed to successfully use the timezone function you mentioned. Just one thing: how do I remove the EST at the end of the time or better still change it to AEST? Also regarding the function, I read on the php site about the possible errors that occur if the timezone isn't valid, eg.
"Note: Since PHP 5.1.0 (when the date/time functions were rewritten), every call to a date/time function will generate a E_NOTICE if the timezone isn't valid, and/or a E_WARNING message if using the system settings or the TZ environment variable. "
Does this mean that if someone uses the form in a different timezone that they'll get an error?
I've just checked the source code and yes the background color css came through but it's just doesn't seem to be rendering.
