How to remove other timezone options in the dropdown during registration

[brijeshrai]

Thanks for the reply.

Yes, I tried to remove the option completely from both member_register & usercp_options template. But unfortunately, whenever a members edits his user cp options and saves it, his timezone is changed to GMT (although I have set default timezone to GMT +4 in Admin CP settings).

Curiously, even the times shown in Admin CP (for scheduled tasks, logs etc.) are in GMT timezone.
