JST vs CST
JST (Japan Standard Time) runs at UTC+9 and CST (Central Standard Time) at UTC−6. CST is normally 15 hours behind JST.
JST stays at UTC+9 all year round — it does not observe daylight saving time. 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.
CST can also refer to China Standard Time (UTC+8); this page covers North American Central Time.
