In forum whenever anybody messages or posts something, the time is displayed wrong, it is showing half an hour back time. The default timezone is set as "UTC" and for India timezone is "UTC+05:30". I tried to change it to "UTC+05:30" and "Asia/Kolkata" but it didn't work. I think this function date_default_timezone_set() will not accept "UTC+05:30" but "Asia/Kolkata" is also not working for me.
