European Daylight Saving Time at

Sorry if this has been discussed here recently…
Do you know whether respects the European DST?

Now it is 17:29 p.m. in Bulgaria, but the current conditions at are from 16:00 p.m. (They are updated every 30 minutes there.)

At the same time, WW says “Observed: 16:00” as well.
Do you know whether this is correct?
