Timezone Errors when syncing with FastMail
Tested against Evolution Ver.: 3.18, 3.20.5
I want to sync my evolution profile on my laptop with Fastmail (www.fastmail.com).
The timezone of my laptop is Europe/Moscow, the timezone of the fastmail account is Europe/Berlin.
In the Evolution app I create an Appointment 1 at 12:00 15.06.2019 and set its Time Zone to Europe/Berlin. After the syncing with Fastmail everything seems to be correct: Evolution shows the time of the beginning as 13:00 15.06.2019, while in Fastmail it looks like 12:00 15.06.2019. That's ok, because there is exactly one hour difference between Europe/Moscow and Europe/Berlin
Now I create another event (Appointment 2, at 14:00) but this time I don't change the default Evolution Time Zone (i.e. Europe/Moscow). After the syncing both Evolution and Fastmail show the same beginning time (14:00), and that is obviously is not true.
Even worse, if I create Appointment 3 (9:00 15.06.2019) and set the Timezone to America/New_York, Evolution shows its beginning time as 16:00, while Fastmail as 9:00 (i.e. can't figure out the real time zone).
