[Check_mk (english)] Problem upgrading from 1.4.0p19 to 1.5.0p4 - timestamp settings?

[Bothari]

I just upgraded from 1.0.4.p19 to 1.5.0p4, and now when I load a page I get
the error below in the logs, and I see this on the page.

Internal error: year out of range

Around line 200 it looks like this:
198 if mode == "abs" or \
199 (mode == "mixed" and abs(age) >= 48 * 3600):
200 return "age", time.strftime(dateformat + " %H:%M:%S",
time.localtime(timestamp))

It looks like the timestamp may be the problem, but I can't trace back to
where it gets passed in.

Anybody seen this before?

Thx,
Joe
