Time often seems to be a problem on virtual servers. :(

Well not often, anyway. :)

The RRD files store time as seconds since the 'epoch'. They have no
knowledge of timezones. Somehow you're attempting to update a file or
files with a data point or points which are older than the youngest in
the existing file(s). That's never going to work with RRD.
This isn't a bug in RRD, it's a fault in the way it's being used.
Did you change the timezone after creating the RRD files and starting
to use them? That might not be the best way of approaching it. :)
