          Issue ID: 15376
           Summary: The time zone name conversions should not be compiled
                    into Phobos
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos

          Reporter: issues.dlang@jmdavisProg.com

As it stands, every time that Microsoft changes the list of time zones that they have, tzDatabaseNameToWindowsTZName and windowsTZNameToTZDatabaseName in std.datetime have to be updated, and it's proven to be a maintenance problem (not to mention that it means that older releases won't work properly with Windows machines that have been properly updated). So, we should introduce a way to get those conversions at runtime rather than compile time (presumably by reading in the windowsZones.xml file that the conversions come from in the first place) and then deprecate tzDatabaseNameToWindowsTZName, windowsTZNameToTZDatabaseName, and TimeZone.getTimeZone.
