Calendar module not displaying correct time for recurring events

[tenmilez]

Platform: Mac Version 13.4.1 (c), Docker Desktop 4.21.1,

Node Version: Node.js v18.16.1.

MagicMirror² Version: 2.24.0

Description: Using an iCal feed from Google calendars, events that are part of a recurring series will not show the correct time unless that event is individually modified.

For example, a weekly meeting at 3pm will show 9am, but if I add a note to that meeting ("this week's topic: hamburgers") then it'll display 3pm properly.

This code snippet is from the iCal/ics output.

Staff Meeting, E Flight Leadership Meeting, and Sprint Meeting are all displaying the wrong times. The iCal/ics for Staff Meeting and E Flight Meeting (sans leadership) are included. E Flight Meeting is displaying correctly, despite being a recurring meeting from the same calendar source, because this particular instance of it has a comment different from the rest of the recurring series.

Steps to Reproduce: Add recurring event to Google Calendar. Get iCal link and add that to MM Calendar module configuration. Timezone might be relevant, I'm using Berlin.

Expected Results: Time of actual event.

Actual Results: Time of event -6 hours.

Configuration: Pretty stock

sounds like the system tinezone is set incorrectly

[tenmilez]

Fixing the system time and restarting the system worked. Interesting that the clock module found the correct time without any configuration, but the calendar module didn't (or, rather, interesting that they don't pull from the same places).

For anyone else that comes along, timedatectl command didn't exist so I followed the instructions in step 1 here to set the timezone via command line.

[sdetweil]

avd you can set the timezone. from the pi desktop by clicking on the date

[sdetweil]

also using the preferences from the top left menu
