The booklet manual makes no mention of the "set time and rate" command; but the included pdf instructions does. No "set time and rate" command is included in the tutorial scenarios; after inserting the "set time and rate" command into the tutorial scenarios, as the first command of the command sequence, via the "edit session rules" button in the top-left of Surveyor, and saving as a slightly-different name in case of a fumble, I found that the time worked fine.
