Problem with Google generated .ics link

@sdetweil You have any thoughts/ideas about what is going on?
EST5EDT looks like some sort of mash up of Eastern Standard Time and Eastern Daylight Time and your node-ical comment look like a more complex issue. Are they intertwined?
Neither of the two would be in my control in just dropping a Google generated URL in the config file.

@ankonaskiff17 can u look at the entry in google calendar and see what the timezone setting is?

how did u create that entry? phone, tablet, computer???

@sdetweil Per Google the only way to get the links is via the PC/Laptop Google Calendar. In their help links they spell that out pretty explicitly and that is how I did it and have always done it. The url generated on settings page is pretty straightforward with only possible error being if you choose public or private url.

As far as time zone, I’ve attached an image but in screen capture the top Primary was and is correct just as shown. The secondary was some oddball city with time being GMT - 7 hours vs primary being GMT -4 so I changed secondary to be another GMT-4 city.

I looked last night, but on phone, and it showed correct time.
Is the 5 in EST5EDT what happens when toggling between EST & EDT & GMT? I dont have any idea if EU has an equivalent to daylight savings time Time Zone .jpg

yes, other countries have DST/STD time shifts…

typically the TZID is specified like this

TZID=America/Barbados
or
TZID=America/Chicago

I see that your ICS has a special definition of the TZID EST5DST

BEGIN:VTIMEZONE
TZID:EST5EDT
X-LIC-LOCATION:EST5EDT
BEGIN:DAYLIGHT
TZOFFSETFROM:-0500
TZOFFSETTO:-0400
TZNAME:EDT
DTSTART:19700308T020000
RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=2SU
END:DAYLIGHT
BEGIN:STANDARD
TZOFFSETFROM:-0400
TZOFFSETTO:-0500
TZNAME:EST
DTSTART:19701101T020000
RRULE:FREQ=YEARLY;BYMONTH=11;BYDAY=1SU
END:STANDARD
END:VTIMEZONE

none of the code we have or use processes the TZ definitions. so that may be the issue…
everything uses the IANA tz definitions.

https://www.iana.org/time-zones

i wrote the mapping code for special MS definitions to IANA definitions used in node-ical and mm calendar
(from this table https://secure.jadeworld.com/JADETech/JADE2020/OnlineDocumentation/content/resources/encyclosys2/jadetimezone_class/ianawindowstimezonemapping.htm)

but nothing accepts the EST5DST format,and neither read the timezone definitions in the ICS file.
