Time period for report (PERIOD)
Specifies the period of time on which to report. The parameter consists of four elements: a starting time and date, and an ending time and date. Data collected prior to the starting time on the starting date and after the ending time on the ending date is not included in the report.
The symbol *N can be used to designate the default value for any of the four elements.
Element 1: Starting time and date
Element 1: Starting time
- *FIRST
- Data records starting from the beginning of the first day (00:00:00) of the collection period are included.
- *SELECT
- An interval selection screen is displayed from which you can select one or more intervals for inclusion. This value is valid only in the interactive environment. If this value is used, the remaining values of this parameter (starting time and date and ending time and date) are ignored.
- time
- Specify the time of the first data record to include in the report, using the format, hhmm or hhmmss, where hh is the hours, mm is the minutes, and ss is the seconds.
The time is specified in 24-hour format with or without a time separator:
- Without a time separator, specify a string of 4 or 6 digits (hhmm or hhmmss) where hh = hours, mm = minutes, and ss = seconds.
- With a time separator, specify a string of 5 or 8 digits where the time separator specified for your job is used to separate the hours, minutes, and seconds. If you enter this command from the command line, the string must be enclosed in apostrophes. If a time separator other than the separator specified for your job is used, this command will fail.
Element 2: Starting date
- *FIRST
- Data records starting from the first day of the collection period are included in the report.
- date
- Specify the date of the first data record to include in the report. The date must be entered in the format specified by the system value QDATFMT, and if separators are used, as specified by the system value QDATSEP.
Element 2: Ending time and date
Element 1: Ending time
- *LAST
- Data records through the end of the day (23:59:59) are included in the report.
- time
- Specify the time of the last data record to include in the report. Use the same format used for the starting time.
Element 2: Ending date
- *LAST
- Data records through the last day of the collection period are included in the report.
- date
- Specify the date of the last record to include in the report. The date must be entered in the format specified by the system value QDATFMT, and if separators are used, as specified by the system value QDATSEP.
