Just to continue this ...
I'm logged in with my TZ set to UTC.
I created an event for 19:00 on Monday 25th.
It showed immediately in the calendar as 19:00 on the 25th.
I went straight away to /feed where it showed as 11:00.
I fear this is going to take more than one of your mythical coffee breaks Mark ;-(
Keep safe, Malcolm.
