[Mono-dev] TimeZoneInfo throwing Object reference not set to an instance of an object but only on Centos

[Arne Claassen]

I ran into what i thought was a bug with an earlier version of 2.4,  
but not think it must be a configuration issue, since it works with  
older and newer builds of 2.4 on Debian and Mac OS X, but my old  
centos 2.4 build and one i just did from 2.4.2.3 sources fail in the  
same way

If i call this:

TimeZoneInfo.Local.GetUtcOffset(DateTime.Now);

i get:

3) Mono.Test.TMisc.Timezone_offset : System.NullReferenceException :  
Object reference not set to an instance of an object

tmp/mono-2.4.2.3/mcs/class/System.Core/System/TimeZoneInfo.cs:387

Is there something that needs to be set up on Centos for TimeZoneInfo  
to function?

thanks,
