CST vs JST
CST (Central Standard Time) runs at UTC−6 and JST (Japan Standard Time) at UTC+9. JST is normally 15 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. JST stays at UTC+9 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.
