Swim is a utility for automatic periodic synchronization of data with internet servers such as Google Calendar (through GooSync), Mobical, Zyb and Ovi. It makes use of the existing SyncML support in the system, and adds timing capabilities, something both S60 and UIQ mysteriously lack! You can set it to sync your data every 15 minutes, every hour, every 4 hours, every 12 hours, daily, or weekly.
