How does the time zone info get updated?

It gets distributed with the base packages, but I haven't figured out how to
keep it up to date.
The info is distributed via IANA.
https://www.iana.org/time-zones
It gets updated several times a year. There were 6 during 2020. When is
unpredictable, often shortly after some government passes a law to change
something with short notice.
I'd expect there to be some mechanism to track the updates but I haven't found
it.
The tz database includes the leap-seconds.list file. That gets updated every
6 months. I'd like to get whatever FreeBSD does for time zones to include
that file so ntpd can use it without having to be concerned with keeping it up
to date. That only works if the zone info is kept up to date.
