apt-daily-upgrade.timer updates

Debian 9

Linode 12GB

Noticed the following on the console when setting up a new Debian 9 server.

systemd[1]: apt-daily-upgrade.timer: Adding 24min 42.662754s random time.
systemd[1]: apt-daily-upgrade.timer: Adding 26min 11.865998s random time.
systemd[1]: apt-daily-upgrade.timer: Adding 32min 37.982157s random time.
systemd[1]: apt-daily-upgrade.timer: Adding 46min 38.526608s random time.

Seems strange that it is adding time by tens of minutes each time up and down.

Not familiar with the service.

IINM, what that's doing is picking a random time between 6AM and 7AM local time to run a daily apt-get upgrade. It's not adding tens of minutes each time, it's adding those tens of minutes to 6AM each time. eg first time is 06:24:42, next is 06:26:11, then 06:32:37 and finally 06:46:38

Thanks…wasn't sure what it was doing.
