Description Colin Valliant 2016-06-10 22:31:15 UTC 
The following happens on reliably on my 10.3-RELEASE system.

I attempted to change my time zone with `tzsetup /usr/share/zoneinfo/America/Los_Angeles` and discovered that /var/db/zoneinfo did not update.

It updates correctly when I run the similar command `tzsetup -s America/Los_Angeles`, and when I select my timezone from the menu with `tzsetup`.

Reproduction steps:

Give the system a known timezone. I'll use "America/Santiago".

# tzsetup -s America/Santiago
# cat /var/db/zoneinfo
America/Santiago
# date +%Z
CLT

Pick a new timezone, such as "America/Los_Angeles".

# tzsetup /usr/share/zoneinfo/America/Los_Angeles # press enter at both prompts

Observe that /var/db/zoneinfo was not updated.

# cat /var/db/zoneinfo
America/Santiago

Observe that the timezone did in fact change.

# date +%Z
PDT

^Triage: to submitter: does this problem still recur on supported versions of FreeBSD?
