Recurring weekly meeting time appears incorrect around the date of changes in time zones

[SSch]

I am setting up a weekly meeting for an international audience, and anchoring it to a 1am UTC start time.  Looking ahead on my calendar I can see that the start time changes from a 1am start time to a 12am UTC start time around the date that other timezones change their clocks by an hour.  (This effectively changes the start time by 2 hours instead of the expected 1 hour change on my local calendar.)  I don't want the UTC 1am start time to change.  I tried anchoring it to 1am GMT but the same problem occurred.  This appears to be a glitch on zoom.  
Is this a known problem and is there work being done to correct it? (Or am I overlooking something?)

hi @SSch ,

I run worldwide meetings and hate it for that week when everyone if changing clocks on different dates.
It can never be completely fixed because not all software relates back to absolute time and can be kept local.
Zoom is pretty correct, isn't it? I have had problems with calendar apps.
I always try to include GMT, and then my UK friends forget they are in summertime!

all the best

John
