Hi Folks, how do you handle the change from standard time to daylight saving time? We are using LotusNotes 6.5.1 and Wine 20041019 on Kubuntu 5.10 Breezy Badger. This is the combination where we experienced the least amount of Bugs. Our hosts run UTC on the hardwareclock and live in the timezone Europe/Vienna, which will change from CET to CEST on sunday. Tests have shown, that calendar entries will get shifted one hour after DST started. If you open an entry there is an info, that the event is located in a different timezone. From a Windows point of view this is perfectly normal, because Windows changes the hwclock to the new version of localtime on every DST event. It doesn't change the timezone it lives in because there is no need to. Linux on the other hand takes care about DST in software. (compare http://tldp.org/HOWTO/TimePrecision-HOWTO/index.html ) And so LotusNotes gets confused. You can even create the time shift effect, if you change the timezone using tzconfig on the fly. This is very annoying and I cannot imagine there is no viable solution out there ... Goesta

When my box was regularly dual booted, this hour difference came in regularly, and I would simply run a hwclock command (hwclock -hctosys) to sync linux, as windows kept the hwclock pretty straight, but linux was always adding or subtracting an hour. One can disable daylight saving in windows, and there is a registry key...

I assume that this worked correctly in previous years when the time shifted. So I assume this is a problem where Linux has been updated so that it knows the new time change dates, but Wine is still using the old ones. Does that sound right? I don't think anyone here is going to be able to help with Wine from 2004, so I think you are going to need to find out where Wine from that vintage keeps the timezone info, and modify it. I know that MS provides the utility tzedit.exe for changing the timezone info in Windows2k. Maybe it will work on Wine?
