[time-nuts] multi time zone display for wall mounting?

[Jim Lux]

I'm looking for an off the shelf commercial time display (or combination 
of displays)..

Needs to display at least 3 zones, in 24 hr form (UTC, Pacific, 
Eastern), and should display Day of Year, as well.

I can feed timecode to it, or even better, if it can ingest NTP.  1 
second precision is more than enough.

Needs to be readable from 20 feet away, but not huge... 2-3" high digits 
are probably in the ballpark.
