Just to close out the thread, Charles mentioned he's using the HamPI distribution (in his first message).
The HamPI distribution is configured to start /usr/sbin/ntpd at boot (via systemd starting "ntp.service"), and
the configuration for that service includes the server pool "debian.pool.ntp.org".
This pool of servers has been established for users of the Debian distribution, which is the base for Raspberry Pi OS.
