By default systemd is using a random time within the specified accuracy 
in order to avoid to many timers running at once.

It's completely unrelated to stopping processes (as far as the 
systemd-as-pid-1 is concerned, the User Manager is just another process 
to be stopped) when the user logs out (the default unless 'linger'ring 
is enabled for the particular user).
