The latest date and time accepted by the server (ISO format).  This value
is also used for expanding non-terminating recurrence rules.

Note that increasing this value will require the DAV databases for
calendars to be reconstructed with the **dav_reconstruct** utility in order
to see its effect on serer-side time-based queries.
