_Problem solved!_
In the GPS/Compass menu I checked the "GPS time sync" box, I thought
this should give automatic DST switching.
But in the "World time" menu, I have home town Amsterdam and destination
Amsterdam, then if you go one menu deeper, there is a check box for DST.
Checking this box immediately switched the time to summertime!
_Why correct time with pictures matters for me
_From the group reactions I see that many members only care about the
correct date._
_Often I take outdoor pictures with the position of the sun not optimal
for preferred lighting.
For a remake later, I use the time to estimate how many hours earlier or
later I have to be there.
_Is DST in the GPS info itself?_
Some members suggested that the camera needs look-up tables to see DST
data of specific countries.
I am not so sure about that.
I did not get a clear answer from Google.
But, GPS was designed for military purposes, it contains time
information, so why not also DST data?
For military on the ground it can be crucial to know the exact local time.
Even when all other systems fail.

_Well, all together it took me a lot more time, than simply adapting the
clock manually! But I gained knowledge!
Thanks for all responds!

Yes it would use UTC most likely. I must add that none of my cameras
have ever transitioned to DST automatically. Maybe I am using it wrong
somehow? Ok. I just looked at my K-3 and though it was set to Chicago
as the city it never changed. It does have DST highlighted though next
to it so I'm confused frankly why it wouldn't kick over. Changing the
home city to NYC adjusted the time ahead one hour, but I think that is
just because I moved the time zone.
Yeah I set it to LA and it changed the time again. Toggling DST on and
off changes the time as well. I think you have to manually enable it.
I just have it on all the time and change my time as necessary. My K-3
was actually set to the wrong time. Not like it really matters to be
honest. I care far more about the date.

Well, yes and no. If you look at that standard Time/Date structure, (Gaud
this is getting into the weeds), if the software is using it correctly it's
stores UTC a flag and an offset to get the local time. I assume that the OS
used by the camera includes a Time/Date object. I also assume it stores the
Timestamp in the "standard" manner. So yes it stores the data in UTC.

Yes, I know. That makes it not UTC.

It pretty much is on UTC. The current time zone is just an offset based
on the home city.

If I had a camera that had gps I would just let it record everything as
UTC rather than try to account for different places. It makes life easier -
one less thing to clutter my head with. In fact even without gps I think I
just leave them on UTC.

Stan, your explanation of GPS sounds logic, thks.
The GPS is also used when shooting ASTRO, but I did not try that yet.
I will check with Ricoh/Pentax why there would be no DST timetable for
the Netherlands. As they should know US could be first but Netherlands are
second!
Anyhow, I will not wait for the software update, but change the time
manually.
Greetz, Jos
