Hi team, I found this "bug" maybe I am lazy to look through the info document.
Correct: $ TZ=UTC date -d "15:00 BST" Mon May 26 14:00:00 UTC 2014 Correct: $ TZ=UTC date -d "15:00 EST" Mon May 26 20:00:00 UTC 2014 Correct: $ TZ=UTC date -d "15:00 JST" (Japan Standard Time) Mon May 26 06:00:00 UTC 2014 Wrong: $ TZ=UTC date -d "15:00 CST" (China Standard Time) Mon May 26 21:00:00 UTC 2014 So the problem is with "CST" in the date STRING.
