Unclear if daylight saving is applied to time zones or if there are fixes offsets

[mc51]

It is not clear whether the depicted time zones include daylight saving time or not. Because the UTC offsets are shown, this seems to not be the case, as the offset suggests those are fixed. However, on the other hand the documentation writes about e.g. Amsterdam, Berlin, Bern, Rome, Stockholm, and Vienna time zone. This suggests that daylight saving is applied, as these time zones use it.
So which one is it?
Also, is there a way to use a timezone according to UTC?
