detect users timezone
----------------------------------------------------------------------------
To detect the user's timezone we need to:
Get the user’s timezone offset (javascript)
Detect if daylight saving time (DST) is in effect at the moment (javascript)
Submit these information to the server, and find the appropriate php timezone identifier based on them (php).
