You should definitely *not* use exotic time zone names such as these.

The official words from the Hosts Requirements RFC:

         There is a strong trend towards the use of numeric timezone
         indicators, and implementations SHOULD use numeric timezones
         instead of timezone names.  However, all implementations MUST
         accept either notation.  If timezone names are used, they MUST
         be exactly as defined in RFC-822.
 
And the timezone names in RFC822 are:

     zone        =  "UT"  / "GMT"                ; Universal Time
                                                 ; North American : UT
                 /  "EST" / "EDT"                ;  Eastern:  - 5/ - 4
                 /  "CST" / "CDT"                ;  Central:  - 6/ - 5
                 /  "MST" / "MDT"                ;  Mountain: - 7/ - 6
                 /  "PST" / "PDT"                ;  Pacific:  - 8/ - 7
                 /  1ALPHA                       ; Military: Z = UT;
                                                 ;  A:-1; (J not used)
                                                 ;  M:-12; N:+1; Y:+12
                 / ( ("+" / "-") 4DIGIT )        ; Local differential
                                                 ;  hours+min. (HHMM)

          Time zone may be indicated in several ways.  "UT" is Univer-
     sal  Time  (formerly called "Greenwich Mean Time"); "GMT" is per-
     mitted as a reference to Universal Time.  The  military  standard
     uses  a  single  character for each zone.  "Z" is Universal Time.
     "A" indicates one hour earlier, and "M" indicates 12  hours  ear-
     lier;  "N"  is  one  hour  later, and "Y" is 12 hours later.  The
     letter "J" is not used.  The other remaining two forms are  taken
     from ANSI standard X3.51-1975.  One allows explicit indication of
     the amount of offset from UT; the other uses  common  3-character

But note that the Hosts Requeirements say:

         The military time zones are specified incorrectly in RFC-822:
         they count the wrong way from UT (the signs are reversed).  As
         a result, military time zones in RFC-822 headers carry no
         information.
