CST to UTC Time — Convert Central Standard Time (US) to Coordinated Universal Time

UTC is currently 5 hours ahead of CST.

On Clockjumper, CST refers to US Central Standard Time (UTC−6). The same three letters are also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5) — 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.

Around January UTC is 6 hours ahead of CST. Around July it is 5 hours ahead of CST. That swing comes from one or both zones observing daylight saving on different schedules — the converter above always reflects the correct offset for the date you pick.
