From SNTP update in a71fa821, the example test uses notification event
(before it simply polled the state in 2 seconds interval). With this
change it is possible that the time gets synchronized before retrying,
i.e. printing "Waiting for system time to be set... (2/15)". (it was
theoretically possible also before this change, but practically never
happened)
