provisioning process.
This is used for periodic checking of firmware and
configuration files to avoid multiple devices from
starting the upgrade process at the same time. When
the device is meant to start the upgrade, the device
randomly selects a number between 1 and the value
set for random_provisioning_time and performs the
check only after the random time.
The valid range is 0-65535. The default value is 120.

hour in the day.
 [powerup] On Power-up Only - The phone tries to
upgrade only after power-up.

Every day at
[provisioning/period/daily/time]
The hour in the day for automatically checking for new
