The problem was, that we in Europe changed to summertime the last sunday
in March, and for some reason the timezone on that M$-machine was set to
CET-2DST but it should have been CET-1DST. I guess the wrong part of the
TZ was just dropped by rdate (the machine is running PC-NFS from
Solaris, and there is nothing whatsoever in the PC-NFS docs on TZ.)
Thanks to all who answered!

In total it was 2 different troubles I had. One machine, running DOS and
PC-NFS, and the other running braindead NT
On the first I set the timezone CET-1DST as mentioned above, but the
other one running Neanderthal Technology, I had to set the timezone to
GMT-2 to get it to understand where it was. (Yes it IS GMT-2 to make it
work, although Sweden is GMT+2 hours)
I knew I would get answers here, although it didn't have any issue
towards FreeBSD, but who thinks I had got ANY answer from M$ ;-)
