Time wrong on 8.1

[the_bertrum]

I think Raspberry Pi OS uses timedatectl.

Code:

pi@moode:~ $ timedatectl
              Local time: Fri 2022-06-24 09:53:51 EDT
          Universal time: Fri 2022-06-24 13:53:51 UTC
                RTC time: n/a
               Time zone: America/Detroit (EDT, -0400)
System clock synchronized: yes
             NTP service: active
         RTC in local TZ: no
pi@moode:~ $

Mine says this:

Code:

pi@Prometheus:~ $ timedatectl
              Local time: Wed 2022-06-22 07:43:21 BST
          Universal time: Wed 2022-06-22 06:43:21 UTC
                RTC time: n/a
               Time zone: Europe/London (BST, +0100)
System clock synchronized: no
             NTP service: n/a
         RTC in local TZ: no

Looks like it isn't synchronising.  I'll have a dig about...
