Just got an update that when using WiFi instead of the mobile operator's network, the syncs are happening smoothly. So this probably is not Funambol/SOGo's concern.
The users will probably have to put up with this. The timezone error could probably be explained as well since the user didn't login into his account using the web gui, and hence his preferences ( that includes timezone) were not initiated. -- [email protected] https://inverse.ca/sogo/lists
