Figure 7-10 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.
