My transaction is unconfirmed from almost a day now and i paid a good fee thinking it will confirm faster.
What wallet or website did you use to send the transaction?
The hours start at the same moment in every timezone AFAIK 
This is not true.

Most of the time zones on land are offset from Coordinated Universal Time (UTC) by a whole number of hours (UTC−12 to UTC+14), but a few zones are offset by 30 or 45 minutes (for example Newfoundland Standard Time is UTC−03:30, Nepal Standard Time is UTC+05:45, and Indian Standard Time is UTC+05:30).
