Thanks for replying, Martyn.
You might be right about March 25 and Daylight Saving.
I did edit settings.
I had asked about it in another thread.
I may have misunderstood or the info was incorrect, I don’t know.
I usually am on GMT+1 and I am east of gmt.(negativ)
At the timezone I have -1.
With Daylight Saving I am on gmt+2
At the timezone I have -2.
These settings may be causing the problem.(See image)
I have "Daylight Saving in use (does auto set) ticked.
Does this mean I don’t have to add another hour to the timezone, it stays -1,
with the setting “Do not auto set time zone” ticked.
