Summary: wine.inf's timezone data is inconsistent with Windows
           Product: Wine
           Version: CVS
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: wine-kernel
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

There are quite a lot of timezones where Wine's registry timezone data (defined
in tools/wine.inf) does not match what Windows has.
Where does wine.inf's current data come from?
Where can one find authoritative data for this?

* wine.inf's TZI field does not match Windows for these time zones:
  Won't this impact email tools?
  Arabic Standard Time
  Azores Standard Time
  Caucasus Standard Time
  Dateline Standard Time
  E. South America Standard Time
  GTB Standard Time
  Iran Standard Time
  Israel Standard Time
  New Zealand Standard Time
  Newfoundland Standard Time
  Pacific SA Standard Time

* wine.inf is missing some time zones:
  Ekaterinburg Standard Time
  Greenland Standard Time
  Mid-Atlantic Standard Time
  Nepal Standard Time
  Sri Lanka Standard Time
  W. Central Africa Standard Time

* wine.inf has an extra time zone:
  Mexico Standard Time 2

* Wine's display name is not in the same format as the Windows one:
  For instance for Tonga Standard Time:
  Windows has: "Display"="(GMT+13:00) Nuku'alofa"
  Wine has   : "Display"="Pacific/Tongatapu"
