Configuration/settings/hide older than
If you want to hide older events in Caldav (to save resources, speed up clients, etc.) define the desired time interval in NUM days:
$c->hide_older_than = 90;
This would set hiding events with "end time" older than 90 days (these events will be unavailable). It can be useful if you use Sunbird or other buggy clients with large amount of Caldav events. For example Sunbird is unusably slow with more than 1500 events and there is no way to limit the number of downloaded events in its configuration settings. In this case this setting speeds up the event loading (~ 1500 events) from ~8 minutes to ~10 seconds.
