[syslog-ng] ISODATE, timezone offset and daylight saving

[Per Jessen]

My local timezone is CET and as we've currently got daylights saving on,
we're two hours ahead of UTC.  So the offset - when using the ISODATE
format - should be +0200.  Instead it is +0100. 

I'm on glibc 2.4.  Distro is SUSE 10.1, syslog-ng is 1.6.8.
The machines hardware clock is in UTC, localtime time CEST.

tournesol:/var/log #  
tournesol:/var/log # date  +%z
+0200


Am I likely to be doing something wrong?  From /var/log/mail:
