CST vs GMT
CST (Central Standard Time) runs at UTC−6 and GMT (Greenwich Mean Time) at UTC+0. GMT is normally 6 hours ahead of CST.
CST is the standard time (UTC−6); when daylight saving is in effect it becomes CDT (UTC−5). The live clock on this page always shows the current offset. GMT stays at UTC+0 all year round — it does not observe daylight saving time.
CST can also refer to China Standard Time (UTC+8); this page covers North American Central Time.
