--- Comment #12 from Dmitry Timoshkov dmitry@codeweavers.com 2009-08-13 21:51:07 --- If Wine can't find a matching DST date in the registry to match the detected one it just uses the detected DST dates and prints a FIXME. I'd consider that a bug in Mono if it doesn't cope with that. But in any case we need to figure out why reporting to the app plain detected DST dates confuses Mono.
