By default, the agenda data of ConfTool Pro will be synchronized with the C4me servers twice a day (in the early morning and around lunch time [CET]).
The process itself takes about 10 minutes.
By request of the organizer, the providers of C4me can increase the update frequency or run an extra update at a certain time.
The application itself checks for updates in the database of the Conference4me servers every 15 minutes.
