Handling of daylight savings

[Rune Nilssen]

If cacti could cope with daylight savings that would be nice, not a very important feature as it only happens twice a year.

But still, for us living in Norway and other countries affected whenever we go from summertime to wintertime we turn the clock back a full hour leaving us with having 0200 to 0300 two times in a row, and same going from winter to summer we suddenly skip a full hour ahead leaving a gap in the graphs.

I've seen people using mrtg having solved this issue, although I have no idea exactly how they did that...

If you server time changes, then you cacti time changes. Simple as that.

This was problem for us in the US as well, so we just set that one server's time zone to be GMT so that it was no longer affected by the DST changes

Yea, I was also testing a new rrdupdate on demand plugin for cacti over the weekend and started thinking about this. In the fall you loose a real hour of work, in the spring, it just looks that way....

Can somebody post to Tobi's forum and see what the recommendation is? I am thinking that GMT might be the answer...

Graph is from this weekend, we are gaining one hour but rrdtool cannot handle one more hour of data in his RRD files so graph shows empty hour.

Just my 2 cents.
