is a from-to time range.
84.1.6 Activating Time Range
A Time Range can have the absolute time range and periodic time range simultaneously. The state of Time
Range can be divided into 4 situations according to whether the absolute time range/periodic time range is
configured.
Situation 1
If a Time Range neither configure absolute time range nor periodic time range, it is called EMPTY. The Time
Range does not exist activating time range.
Situation 2
If a Time Range doesn't have the absolute time but has periodic time range, the activating time range of the
Time Range is the total time ranges of the periodic time range.
Situation 3
If a Time Range doesn't have the periodic time but has absolute time range, the activating time range of the
Time Range is the total time ranges of the absolute time range.
Situation 4
If a Time Range neither have the periodic time nor the absolute time range, the activating time range of the
Time Range is set intersection of the set union of the absolute time range and all periodic time range.
The complementary set of the activating time range of a Time Range is considered as non-activating time
range.
If the system time is in an activating time range of a Time Range, the Time Range is active; if a Time Range
has the activating time range but the system time does not in the activating range, the time range is inactive;
if a Time Range does not have the activating time range, the Time Range is empty.
When a Time Range changes among inactive, active and empty, the Time Range is changed. Otherwise, the
Time Range is unchanged.
