Thanks Sven.

timedatectl(1) yields:

          Local time: Thu 2019-08-08 12:16:51 PDT
      Universal time: Thu 2019-08-08 19:16:51 UTC
            RTC time: n/a
           Time zone: America/Los_Angeles (PDT, -0700)
     Network time on: yes
    NTP synchronized: yes
     RTC in local TZ: no

Does this mean ntp(1) is running periodically?

    Thanks,

    John

BTW, the reason for the question is that the RPi documentation claims
ntp(1) is run ONLY AT BOOT to set the system time. I have a 3b+ that
has been running many weeks with less than a 100 mS system clock
error, implying that ntp(1) is run periodically. Hardly possible with
commodity timing components.
