Hi Russell,

I developed an open source .NET API which you might find helpful with your C# application which is available at:
http://www.codeplex.com/zoneinfo

I have a codeproject article about it as well at:
http://www.codeproject.com/KB/locale/zoneinfo_dotnet_api.aspx

You can read through the code if you are interested in seeing how I interpreted this information.

Kind regards

Mark Rodrigues

Russ,

I think you'd be better off parsing the compiled data, it's a lot more consistent.

Thanks,

Hi,

I hope i'm not wasting your time. I'm attempting to read the tz database into a c# application, and I'm not sure how to interpret this entry:

Zone Australia/Hobart    9:49:16    -    LMT    1895 Sep
            10:00    -    EST    1916 Oct 1 2:00
            10:00    1:00    EST    1917 Feb
            10:00    Aus    EST    1967
            10:00    AT    EST

What is the significance of the "1:00" on the row ending in "1917 Feb". Do I just add this to the 10:00 offset?

Thanks,
Russell
