Re: Impact of daylight saving on mrtg

by Firdous Saleheen :: Rate this Message:

Hi Tobi,

So there will be no gap in MRTG graph when forwarding the clock and no
overlapping when it will come back to the original time??

Btw, our MRTG server clock will be forwarded 1 hour in that moment(daylight
saving).

Your suggestion would be highly appreciated!

Cheers,

Firdous Saleheen

rrdtool (and mrtg) work at UTC internally, so daylight saving time
has no effect on them ...
