Hi, This is my first post in this mailing list so please redirect me to an etiquette page if I do anything wrong :) I am using the tzdata2008b.tar.gz distribution from the 24/03/2008. Using the Australia/Melbourne zone, it seems to imply that the format of the zone is EST regardless whether I am in day light savings or not. According to this article [http://www.australia.gov.au/Time_Zones] the format should be AEST except during daylight savings in which case it is AEDT. It also indicates that there may be problems with all the zones in the Australian region. So a couple of questions: 1. What is the best way for me / us to verify this is right? Is that fact that it is on a government web-site enough? 2. If this is correct what is the best way to update the data file. I am more than happy to change it and send back for review and incorporation if required / appropriate. If you need any more from me please let me know. Thanks and kind regards Mark Rodrigues http://www.codeplex.com/zoneinfo
