sure Tobi, this is what I explained to Mats in the first place.

BTW: I have seen several posts on this list where people work
with databases that span long periods of time (like 50 years)

I'm wondering why rrdtool does allow to create databases that
venture out of the unix time stamp range? Shouldn't there be
a range check on database creation?

And, BTW: why rrdtool doesn't allow to fetch data before 1980?
I understand that rrdtool didn't exist back then, but somebody
potentially could want to import historical data and since the
time stamp is perfectly valid I don't understand the limitation?
