    Re: Time zone by letter and DST
    From: Greg R_

    I believe the letter designations are based on the offset from GMT
    (i.e. zone description) for the current time in use, without any
    reference to whether DST is being observed or not.
    Couldn't find any definitive answer to the question of this thread
    topic, so I'd guess the logical (and technically correct) answer would
    be that the letter designator would change during periods when DST is
    in effect, and revert back to the "normal" one when it's not.
