Yeah, at 01:00 UTC to be precise. See http://www.vandenbogaerdt.nl/rrdtool/summertime.php for how things look when all is right. It displays its labels at a fixed interval, in your case of 24 hours. Sunday 00:00 METDST + 24hrs equals sunday 23:00 MET. That's sunday twice, as your case shows. It does indeed look weird. It is a displaying problem, not a data problem so I wouldn't worry about it too much if I were you. It will go away as soon as all summertime has disappeared from your graph. I do seem to recall that in the past, rrdtool would display its labels like so: | | | | | | | | | | ...... | | | | | | | ... 22:00 00:00 02:02:00 04:00 06:00 ... 20:00 22:00 00:00 02:00 ... (summertime to normal time, overlapping 02:00 twice) | | | | | | | | | | ...... | | | | | | | ... 22:00 00:00 04:00 06:00 08:00 ... 22:00 00:00 02:00 04:00 ... (normal time to summertime, missing 02:00 as there is none) I may not be 100% right here but the key factor is that it would continue to show local time plus a fixed interval. This means midnight would be at the right place, labels in your case would have been correct. But it would require fixing those other two problems I just show. Anyway, I'm just guessing here but I think this is why the new method is being used.
