How FROM and TO Relate to the Log and Historical Files

Reports cannot start earlier or end later than the data in the input file used. The dates and times that your report covers are printed at the top of each page, following the FROM and TO headings.

The FROM and TO commands relate to the log and historical files as follows:

• If the FROM and TO dates or times are outside the range of the data in the input file, the report covers the data in the file closest to the dates and times specified.
• If no FROM and TO dates are specified, the report covers all records in the input file.
• If dates but no times are specified in the FROM and TO commands, the report covers all records within the specified dates.

The FROM and TO commands have the following syntax:

FROM time
TO   time

time

Specifies the date and time, in either of two formats.
