All records in an accounting file are time-stamped with the time the record was logged in the file. The /SINCE qualifier selects only the records time-stamped on or after the specified time. You can specify an absolute time, delta time, or a combination of the two. If you omit the time, 00:00 hours on the current day is used. See also the /BEFORE qualifier, which selects records time- stamped before a specified time.
