JustRelate CRM supports all-day appointments (All-day flag in the form header) and their synchronization with the groupware. The designation "All-day" is interlocked with the "Begin" and "End" fields. If the flag is set, the begin is set to 0:00:00, and the end to 23:59:59. If the time is modified, the flag is reset. Changes to the day are allowed.
