I'm forwarding this message from Ian Davies. --ado From: Ian Davies [mailto:iand@PartyGaming.com] Sent: Thursday, October 09, 2008 3:20 To: Olson, Arthur David (NIH/NCI) [E]; markdavis34@home.com Cc: Ian Davies Subject: Mapping Localised Windows TZ to TZID Gents, My developers are using the following mapping to [establish] then map a Windows TZ to a unix TZID, [Olson], LDML etc. http://unicode.org/cldr/data/diff/supplemental/windows_tzid.html The issue is the only registry entry they have located so far has the Windows TZ stored as a text string and this is localised on non English Windows. In Windows is there a language [independent] reference for the TZ that machine is currently set to that we could utilise? Please also pass on this enquiry to any parties who may be able to help.
