MMM-CalendarExt3 BST Timezone issue
-
I will have to pick this up again tomorrow. i will run the debug when i get home from work.
is there anything I am looking for in particular? -
@shall_ because there is a rrule
the string
dates: …
documents the dates returned from the rrule.between function… yesterday plus 1 year
is the window we create to get recurring events -
@shall_
CX3 doesn’t parse ics file directly, so probably the default calendar app (or any event provider) must have responsibility.But for an instant solution, you can use
preProcessor
orevent payload
to make a hotfix by force.BEFORE
/* in your CX3 module config */ preProcessor: (event) => { if (["SomeCalendarName", "AnotherCalendarName"].includes(event.calendarName)) { event.startDate = Number(event.startDate) - 1000 * 60 * 60 event.endDate = Number(event.endDate) - 1000 * 60 * 60 } return event }
AFTER
If all your calendar has that issue, you can omit if statement.
preProcessor: (event) => { event.startDate = Number(event.startDate) - 1000 * 60 * 60 event.endDate = Number(event.endDate) - 1000 * 60 * 60 return event }

@MMRIZE Thanks for your reply.
The timed calendar events with a start/finish time show the correct time with no issue.The issue solely lies with all-day and multi-day events.
All of these events during DST showed correctly, as soon as the timezone changed to BST. They now all rollover into the following day, so my 5 day events are now 6 days, 2 days are now 3, single days 2. -
@shall_
Can you send me the ics file? (eouia0819@gmail.com) -
@MMRIZE i have emailed it over

Is MagicMirror installed directly to your Pi, or are you running it inside a Docker or other container? I originally had a similar problem with my MM configs all set properly, and my system time set properly, but for some reason I needed to also force the Docker container to the correct timezone with environment variables in the docker-compose file:
environment: - TZ=America/Los Angeles - SET_CONTAINER_TIMEZONE=true - CONTAINER_TIMEZONE=America/Los_Angeles
Obviously you’d want a different timezone, and you’re probably running MM on your Pi without using Docker, but maybe it’ll help.

@shall_ @alaric10000
It happens when the event is regarded as FulldayEvent but not to start at 0 O’clock. I updated the module to fix it.

Update the module and check it. -
Finally I found what was wrong.
The issue lies in the wrong parsing logic from the default calendar module about repeated full-day events with TimeZone by RRULE.
If you have installed CX3 v1.8.2, Reinstall again or back to 1.8.1 (I rolled back again to 1.8.1)
Then see this;

@MMRIZE but… for full day, you ignore the time… or reset it to 00:00:00
