I have two.

1. radioshack voxclock 3.  Purchased 1993.  This is an ac powered clock
with battery backup.  Has served me well for over ten years.

2. Atomic clock purchased from lifestyle fascinations.  Good clock with
british female voice.  However, one major problem.  Covers all four major
us timezones, but can't disable daylight savings.  Since I live in Indiana,
(one of the few sensible states without daylight savings), this is a problem.
I would like to find an atomic clock which supports disabling daylight
time, and also will support utc.  Would be awefully handy to have an atomic
set to utc for remembering radio events and such.
