Calendar - only all day events showing - moment timezone issue

MagicInMe

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”}

@magicinme yes, fun times. Microsoft has lots of non-standard timezone definitions.

I just put fixes into the ical parser we use.
hopefully they will be published soon do we can update the dependency list.

MagicInMe

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

sdetweil

@magicinme I don’t know. I hope soon so we can include it in the next release on April 1st

MagicInMe

@sdetweil perfect, thanks a bunch!

sdetweil

@magicinme the fix did NOT make 2.15, as the repo published the fixes JUST last night

if u want to test/run with the new code do

cd ~/MagicMirror
npm install node-ical

restart MM

same for 2.14 or 2.15

MagicInMe

@sdetweil Thank you! I am running it now, I’m still getting

[12.04.2021 08:39.20.358] [ERROR] Moment Timezone has no data for Customized Time Zone. See http://momentjs.com/timezone/docs/#/data-loading/.

but it appears as though there are fewer errors and the module does seem to be displaying my events. Perhaps I have some buggy iCal events in there. If I get a chance to dive in more, I’ll see what I can update.

sdetweil

@magicinme can u send me your ics file. I thought we put fixes in 2.15 for this

my email is the same user ID at gmail

oh, wait, the fixes are in node-ical

do

cd ~/MagicMirror
npm install node-ical

the restart mm

It appears as though the issue arises when the calendar has custom (non-standard) timezones. node-ical parses the file properly however there is no code to digest the parsed VTIMEZONE entries and apply them to referencing events. Looking at this VTIMEZONE entry, it seems rather hack-y so it probably is not worth it to parse. I notice that all of the weird entries are originate from an iPhone.

Here’s an example ical file of an offending text:

@magicinme none of the libraries digest the tz definitions. mm doesn’t either.
