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.
