TimeZone.getDisplayName() does not always return a description of
the timezone abbreviation but instead somtimes returns GMT+/-#
   
The 3 letter abbrevaiton was always explained.
 For example:
    In Java: AST is Alaksa Standard Time
    Other places: AST is Altantic Standard Time
   
    Not having this description has caused some problems.
    It is missing for: ACT, AET, AGT, ART, BET, BST, CAT, EAT, EET, IST, MET,
                       MIT, NET, NST, PLT, PRT, SST, UTC, VST
