Time intervals in Kerio MailServer restrict all scheduled tasks to certain time ranges. They are not intervals in the true meaning of the word. They are a group containing any number of single or repeating time ranges. Time intervals can be defined in the section.
When defining a time interval three types of time ranges (subintervals) can be used:
— interval has explicit start and end dates, it does not repeat
— interval repeats every week (on selected days)
— interval repeats every day (in selected hours)
If a certain time interval consists of multiple ranges of different types, it is valid in the time defined by the intersection of absolute ranges with the union of daily and weekly ranges. In symbols:
(d1 | d2 | w1 | w2) & (a1 | a2)
where
d1
, d2
— daily ranges
w1
, w2
— weekly ranges
a1
, a2
— absolute ranges
You can create, edit or delete time intervals in section.
Clicking on the
button will display the following dialog window:Name (identification) of the time interval. You can enter a new name (create a new interval) or select an existing one and add a new item to it.
