When a foreign timezone is used in a calendar event, CGP is not displaying the event, and opening the event from the folder view gives the error "VTimeZone syntax error".

Lightning has the same problem, it can't import CGP timezones, SyncKolab reports a parse error.

For now the only way to have those two products working together is to strip out the timezone information and convert the times to GMT. For most of the events this is not a problem, except maybe for the cross-DST recurring events.

The foreign timezones issue is wll known in the lightning-team and ctalbert is working on it but it's quite a complicated problem. Afaik, Communigate understands foreign timezones and stores them, it´s lightning who isn´t able to store foreign zone-definitions.

Thanks for the info. However, converting the VTimeZone with a Mozilla TZID to a VTimeZone with a CGP TZID is not possible.

There is 396 different Mozilla TZID but only 60 CGP ones (in Services/TimeZones.data), and the timezone information for a particular region isn't always the same.

Can CGP rely on the Timezone definition (TZOFFSET[from/to] and RRULE) instead of relying on the TZID? I'm not sure how interoperability can be achieved if each product can only understand its own TZIDs since TZIDs are not a public definition.

Hello,

I modified the extension again to fix the VTimeZone error problem. Now, while being converted to the CGP format, all dates are converted in UTC and timezone information is removed.

Events created by CGP seems to always be created with UTC dates, without timezone information.

Unless those are recurrent events that cross DST on/off transition date.
