Daylight Saving Time

Morning!

Since daylight saving time happening yesterday, all of my graphs appear to be 1 hour ahead and the graphs in a number of them don’t appear to be showing the values / data points.

DB timestamps:

Grafana graph:


Are you certain that the data in your back-end data store has timestamps in
UTC?

If not, this is a typical example of the problems local timestamps cause.

PS: Apologies if the answer to this was clear from your screenshots, but
images don’t get sent to mailing list users (not even as clickable links), so
I have no idea what your screenshots show.

Thanks @pooh. Think my MYSQL DB is the culprit after further checking. It has the system_time_zone as GMT and not UTC…
