JST vs BST
JST (Japan Standard Time) runs at UTC+9 and BST (British Summer Time) at UTC+1. BST is normally 8 hours behind JST.
JST stays at UTC+9 all year round — it does not observe daylight saving time. BST stays at UTC+1 all year round — it does not observe daylight saving time.
BST is the summer time of the United Kingdom; in winter the UK is on GMT (UTC+0).
