No, you should use the time zone identifier of "Europe/London" as that is the time zone observed by the UK. It should then be accurate for both standard time and daylight saving time.

(As a general note, if you're doing any significant date and time work in Java, it's worth checking out Joda Time - a much nicer API than the built-in one.)

assert TimeZone.getTimeZone("BST").getDisplayName().equals("Bangladesh Time");
