You could use ClockMin and make the UWCS policy not apply around the
time of your nightly reboot. Something like: ifThenElse(ClockMin < (11 *
60) || ClockMin > (2 * 60), UWCS_START, TRUE)

The above, or something like it, should make the UWCS_START policy apply
between 2AM and 11PM, and between 11PM and 2AM the machine will just
accept jobs. You'd probably want to change TRUE to something that takes
into account CPU load, just not KeyboardIdle.

Best,
