darner's root timezone changed

[Pierre Abbat]

Darner's periodic output has been coming around 5:00 EST instead of shortly 
after midnight, which is 5:00 UTC. Here's a listing of the snapshot directory 
(minus the symlink arrows, which make it wider than the screen):

This change coincided with installing the kernel and world which I had 
compiled a few days before. (The missing days are caused by bringing the 
computer to a friend's house and back.) Zyxomma did not change the time of 
periodic when I upgraded its kernel.

On zyxomma:
# echo $TZ

# date
Sun Jan 19 05:56:56 GMT 2014

On darner:
# echo $TZ

# date
Sun Jan 19 00:57:02 EST 2014

Any idea why?
