      fraction        = ( DOT / COMMA ) 1*(%x30-39)
      g-time-zone     = %x5A  ; "Z"
                        / g-differential
      g-differential  = ( MINUS / PLUS ) hour [ minute ]
      MINUS           = %x2D  ; minus sign ("-")

   The <DOT>, <COMMA>, and <PLUS> rules are defined in [RFC4512].

   The above ABNF allows character strings that do not represent valid
   dates (in the Gregorian calendar) and/or valid times (e.g., February
   31, 1994).  Such character strings SHOULD be considered invalid for
   this syntax.

   The time value represents coordinated universal time (equivalent to
   Greenwich Mean Time) if the "Z" form of <g-time-zone> is used;
   otherwise, the value represents a local time in the time zone
   indicated by <g-differential>.  In the latter case, coordinated
   universal time can be calculated by subtracting the differential from
   the local time.  The "Z" form of <g-time-zone> SHOULD be used in
   preference to <g-differential>.
