I am wandering about timezones. A live in Finland, timezone UTC+2, and the server in question is also there. An API call added a participant having 'valid from' set at 10:50. API calls for invitations at 11:15 and 12:15 said "Token not valid yet", API call at 13:15 sent the invitation.
So I do not quite get this. Why there is the setting for timezone at the first place, usually programs use the system setting?
