@sdetweil perfect, thanks a bunch!

@sdetweil Great, thank you! What do you think the ETA would be? Just for my own sanity

In my magic-mirror I am using the default calendar module and am connected to a microsoft (Outlook.com) calendar. It is only showing events from a birthday calendar (all-day events). It appears as though moment-timezone is struggling to parse the timezone information from the event. Any ideas as to what might be the problem? The log has a million entries like the one below:

event={“type”:“VEVENT”,“params”:[],“uid”:"[REMOVED]",“summary”:"[REMOVED]",“start”:“2021-07-12T14:00:00.000Z”,“datetype”:“date-time”,“end”:“2021-07-12T15:00:00.000Z”,“class”:“PUBLIC”,“priority”:“5”,“dtstamp”:“2021-03-26T00:58:12.000Z”,“transparency”:“OPAQUE”,“status”:“CONFIRMED”,“sequence”:“0”,“location”:"",“MICROSOFT-CDO-APPT-SEQUENCE”:“0”,“MICROSOFT-CDO-BUSYSTATUS”:“BUSY”,“MICROSOFT-CDO-INTENDEDSTATUS”:“BUSY”,“MICROSOFT-CDO-ALLDAYEVENT”:“FALSE”,“MICROSOFT-CDO-IMPORTANCE”:“1”,“MICROSOFT-CDO-INSTTYPE”:“0”,“MICROSOFT-DONOTFORWARDMEETING”:“FALSE”,“MICROSOFT-DISALLOW-COUNTER”:“FALSE”}
