Timezone problems (Calendar)

I’ve created a calendar event at the WebMail Calendar Service but i got the following error message when try to sync with eM Client calendar:

21:58:37 MailExceptions.Exception: Erro na sincronização da pasta CalDAV: System.InvalidOperationException: A operação não é válida devido ao estado atual do objeto.

Server side timezone is “America/Argentina/Buenos_Aires”, local timezone is America/Buenos_Aires".

Hi Ronison,
may I ask what kind of account is this calenadar connected to?

It’s a CalDAV service provided by an e-mail solution based in Tine 2.0.
Calendar events created using eM Client works fine and syncs normally w/ server.

Apparently , the application does not recognize timezones in the format " America/Sao_Paulo " or " America/Argentina/Buenos_Aires ", but only in Windows format like “E. South America Standard Time” or “Argentina Standard Time” (listed using command “tzutil /l”)…
