Main settings tab
In the main settings you can give your trigger a description which will distinguish several triggers from each other in a trigger list. You can also choose between the Interval and Custom type triggers. Once selected, the other tab will be grayed out.
Interval tab
This time trigger is a result of trying to simplify the Custom time trigger. Also some features are added; like running something the last day of every month.
Custom tab
VC2 users may be used to the Custom time trigger, which allows setting of time details when a job should be triggered.
Expiration tab
The expiration date/time for the time trigger may be set. Also the handling (inactivate/delete) of the expired trigger is selected.
