      Platform: Raspberry Pi 4 Model B Rev 1.4 8gb
      Node Version: v14.18.2
      MagicMirror Version: v2.17.1
      Description…
      I added a couple of Google Calendar private iCal URLs to the Calendar module

      {
	module: "calendar",
	header: "",
	position: "top_left",
	hideTime: true,
	config: {
		fullDayEventDateFormat: "MMM Do",
		calendars: [
			{
				symbol: "...",
				url: "https://calendar.google.com/calendar/ical/.../private-.../basic.ics"
			},
			{
				symbol: "...",
				url: "https://calendar.google.com/calendar/ical/.../private-.../basic.ics"
			},
			{
				symbol: "",
				url: "https://www.vic.gov.au/sites/default/files/2021-09/Victorian-public-holiday-dates.ics"
			},
			{
				symbol: "clock",
				url: "https://www.vic.gov.au/sites/default/files/2021-03/Daylight-saving.ics"
			}
		]
	}
},

      (fyi, the source of the issue is from the second private calendar, but I’ll provide some more details below)

      When running MM, the event

      BEGIN:VEVENT

      is displayed -11 hours (ie the day before @ 2200 instead of 0900), all other events (so far) from the same calendar are been presented correctly

      *nb: K6 should be Sunday 09:00, living in Australia/Melbourne Daylight Savings Time, +11)

      Thinking I had screwed something up, I download a copy of the iCal file from Google and run it through another library (biweekly Java Library) and had no issues

            @sdetweil Yes, I figured that, but my experience is in Java and Swift, so I went for what I had and just wanted to see if it was an issue with the source data 😉

                @rustyknight im pretty sure the k6 problem is caused by the repeating rule.

                the rule engine we use assumes start date/time is in local time format not utc.
                everything else is utc,
                so there is a double conversion cause it takes the date from one and time from another…

                I also assume your system time is set to Melbourne…

                  @sdetweil Yes, I went through all the PI settings and made sure they are set to Melbourne.

                  I’m not overly concerned about as I’m only testing this stuff out, my wife will have whinge though 🙄
