Argument for “Automatic updates detection frequency”
This sets the time to “Check for updates”. This could work as well, as it would check for updates at the scheduled time and therefore install if some were ready.

Automatic Update Detection Frequency
This policy specifies the hours that Windows will use to determine how long to wait before checking for available updates. The exact wait time is determined by using the hours specified here, minus 0 to 20 percent of the hours specified. For example, if this policy is used to specify a 20-hour detection frequency, then all WSUS clients to which this policy is applied will check for updates anywhere between 16 and 20 hours.
