Description
In the latest snapshot as of now, certain RRD graphs cannot be rendered due to negative distance on the time axis (i.e. for some of the time intervals the end is before the start).
Updated by Jim Pingle over 13 years ago
As discovered in this thread: http://forum.pfsense.org/index.php/topic,27910.msg146548.html#msg146548
The time rendering issue seems to only happen between 12am and 12pm, so if you check it after noon, the graphs are OK and you can't reproduce the issue.
Error message from the thread (and mine is similar if I check it before noon)

We're seeing this too. Our RRD graphs were fine up until yesterday's release.

I've disabled the 12 hour timespan graph for now. I'll have to look into it later.
Updated by Seth Mos over 13 years ago
in place of the 12 hour timespan I've made the 8hour timespan instead, which is easier to craft. This also has to do with #812
Needs feedback

hmm, the quality RRD doesn't seem to be working recently, although for entirely different reasons I'm sure.

All RRD graphs are working fine @ Pfsense nanobsd 1G 2.0-RC3 (i386) built on Wed Aug 3 20:04:02 EDT 2011
