Summary0013804: Timezone Issues with TbSync
DescriptionThis issue is forwarded from another issue at

Here is the summary from the other issue:

"Tine will use the LOCAL time of the event in the global view, which is not clever. Thunderbird always calculates the time of the event in the default timezone of the user and only displays the timezone specific time in the edit window (as Tine does)."
"The above finding results in "moving events" if the timezone is changed. Which is again a bad idea."
"Also, Tine does not obey timezones of incomming events. "
"Tine may use its default TZ to display the times in the global view, but it may not change the TZ itself. Furthermore, it would be nice, if Tine would actually include Europe/Moskau in the standardName/daylightName (Tine is using IANA names internally, so why not send them?). Above could also be, India/Mayotte... without a name it is hard to know..."

hi estradis, thanks for the report. what is the advantage of using tbsync over the stock thunderbird/lightning sync?

I'm not sure about this:
"Also, Tine does not obey timezones of incomming events."

i'll pass this to Cornelius as TZ is his special area ;)
