IST to UTC Time — Convert India Standard Time to Coordinated Universal Time
UTC is currently 5 hours and 30 minutes behind IST. This offset stays the same all year — neither zone shifts for daylight saving in a way that changes it.
UTC is currently 5 hours and 30 minutes behind IST.
Abbreviation disambiguation
On Clockjumper, IST refers to India Standard Time (UTC+5:30). The same three letters are also used for Israel Standard Time (UTC+2) and Irish Standard Time (UTC+1) — check the city or UTC offset to be sure which is meant.
On Clockjumper, UTC refers to Coordinated Universal Time — the global reference from which every other zone is expressed as an offset. It never shifts for daylight saving. GMT is equivalent to UTC for everyday use, though in the UK "GMT" also names the winter time, with clocks moving to BST in summer.
