Pierre,

the reason is twofold:

1) The timezone wasn't explicitly set on the box (using tzsetup(8) for  
example), i.e. there is no /etc/localtime file.

2) In the case when no timezone is set, the whole code will fall back to  
the "POSIXRULES" zone, which is (and always was) "America/New_York", or  
EST, per  
http://gitweb.dragonflybsd.org/dragonfly.git/blob/HEAD:/share/zoneinfo/Makefile  
(saying "POSIXRULES=America/New_York"). But this never really worked,  
which seems to have been a bug, until the most recent tzcode upgrade,  
after which it finally started working.

Regarding a solution, I think the best way out is to explicitly set the  
time zone on this box using tzsetup(8) and choosing UTC there, or any  
other zone you prefer.

Alternatively, to restore the previous behavior globally, we could also  
set POSIXRULES to UTC in the Makefile, about which I have no opinion.
