说明：  Is it Standard or Daylight time? This script fills in the correct middle letter of the time zone designation so that either an "S" is shown for Standard, or a "D" for Daylight time. The first function of the script may be used independently if you just need to know in which segment of the year a given date/time is. Adjusted for the new 2007 time changes.
