It is not. I did not configure anything in particular. Sometimes, perhaps 
When the associated timer service has an error, but not always, the message 
is absent. By an error I mean, for example, network is not reachable during 
service run. Or a particular remote host is not responding.

By a user service I mean a service that its timer is controlled by a regular 
user, uid >= 1000. And its journal can be seen by that regular user with 

    journalctl --user -u associatedTimerService --since today

As I wrote, perhaps the message is absent when the service has terminated 
with an error. But that association is not conclusive.
