Yes is the quick answer. When I am in the Channel Tunnel travelling to France I switch the time zone to GMT+1 and retain the DST tick box. When returning from France back to GMT (irrespective of whether we are in summer time). If we ever stop using daylight saving time we’ll be out of step with Euro...

Did exactly the same, within weeks.
