Dell PowerEdge M420 Reference Manual page 1609

When both periodic and absolute time entries are specified within a time
range, the periodic time entries limit the time range to only those times
specified within the periodic time range and bounded by the absolute time
range. In this case, the absolute time entry specifies the absolute start and
end dates/times and the periodic entries specify the start/stop times within
the limits of the absolute time entry dates and times.
If a periodic time entry is added to an active time-range with an existing
absolute time entry, the absolute time entry immediately becomes inactive.
For example, an administrator applies a absolute time-range configured for a
week's work hours ( 08/09-08/13 9am to 6pm) and later adds multiple
periodic entries for same days configured individually (Monday, Tuesday,
Wednesday, Thursday, Friday) but with after-work hours (9pm to 11pm) .
The administrator wants to permit/deny HTTP traffic for this time-range, but
the entire time-range is invalid due to conflicting entries. The absolute entry
is forced to inactive because the periodic entry time is not yet in effect.
