GMT +5:30...!!!

You must have set ur Mobile Time after setting GMT +5:30...DO u know wat it actually means???? Lets find out!!!

GMT stands for Greenwich Mean Time.
# Greenwich Mean Time (GMT) is a time system originally referring to mean solar time at the Royal Observatory in Greenwich, London, which later became adopted as a global time standard.
# It is arguably the same as Coordinated Universal Time (UTC) and when this is viewed as a time zone the name Greenwich Mean Time is especially used by bodies connected with the United Kingdom, such as the BBC World Service.# There are 40 time zones starting from UTC -12 to UTC +14...some with 30 minutes gap.
# So when we say GMT +5:30 , it means 5 hours 30 minutes ahead of GMT time(the time in London).
# India had 2 time zones Bombay Time and Calcutta time till 1905...after which single time zone was selected called IST (GMT +5:30).
