Determines the dates for the query, in conjunction with the Time1 argument.

If the Time1 argument contains the starting time, specify the end time of the query.

If the Time1 argument is set to REL (relative time), specify the time relative to the base date. The required form is:

###T(##:##:##)

where

  • ### = Number of time units from the date/time.

  • T = Time unit (d=days, h=hours, m=minutes, and s=seconds).

  • (##:##:##) = Time that the time units are relative to. This time and the base date are used together to determine the date/time. To specify the now as the date/time, leave the parentheses empty.

Examples are:

+20m(5:00)

Starting at 5:00 of the BaseDate, ending 20 minutes later.

-20m()

Starting 20 minutes ago, ending now.

-20m(#Time)

Uses the configured base time.

This argument accepts date/times as real (double) numbers, in addition to dates.
