Starting and Ending Time for Collecting Monitoring Data
yyyyMMddhhmm
yyyyMMdd indicates the year, the month, and the day. hhmm indicates the
hour and the minute.
If yyyyMMddhhmm is omitted on the left of the colon, the starting time for
collecting monitoring data is assumed. If yyyyMMddhhmm is omitted on
the right of the colon, the ending time for collecting monitoring data is
assumed.
+hhmm
Adds time (hhmm) to yyyyMMddhhmm if yyyyMMddhhmm is specified. For
example, 200601230000+0130 indicates Jan. 23, 2006. 01:30.
Adds time to the starting time for collecting monitoring data, if
yyyyMMddhhmm is omitted.
-hhmm
Subtracts time (hhmm) from yyyyMMddhhmm if yyyyMMddhhmm is
specified. For example, 200601230000-0130 indicates Jan. 22, 2006.
22:30.
Subtracts time from the ending time for collecting monitoring data, if
yyyyMMddhhmm is omitted.
If the last two digit of the time on the left or right of the colon (:) is not a
multiple of the sampling interval, the time will automatically be changed so
that the last two digits is a multiple of the sampling interval. If this change
occurs to the time on the left of the colon, the time will be smaller than the
original time. If this change occurs to the time on the right of the colon,
the time will be larger than the original time. The following are the
examples:
– If the time on the left is 10:15, the time on the right is 20:30, and
the sampling interval is 10 minutes:
The time on the left will be changed to 10:10 because the last two
digits of the time is not a multiple of 10 minutes. The time on the right
will remain unchanged because the last two digits of the time is a
multiple of 10 minutes.
