My 10-STABLE version is actually a month or so older than 10.1-RELEASE
(which was announced on 14 Nov 2014):

Here's the output of `svn info' (I haven't updated since I compiled base
and kernel):

In my case, /etc/localtime is a copy of the file in /usr/share/zoneinfo.
IIUC, `mergemaster -i' is supposed to automatically run `tzsetup -r' to
update /etc/localtime from /var/db/zoneinfo.  I have no TZ in the environment.

$ ls -li /etc/localtime /usr/share/zoneinfo/Europe/Vienna 
 211986 -r--r--r--  1 root  wheel  2211 Oct  9 20:42 /etc/localtime
7892691 -r--r--r--  1 root  wheel  2211 Oct  9 20:36 /usr/share/zoneinfo/Europe/Vienna
$ cmp /etc/localtime /usr/share/zoneinfo/Europe/Vienna 
$ echo $?
0
$ cat /var/db/zoneinfo 
Europe/Vienna
$ printenv | grep TZ
$ echo $?
1
