Add timezone to voicemail display

The voicemail box lists seconds past epoch and a UTC date.  The UTC
date isn't terribly useful because people want to see the local time
of the message so use a static timezone to change the message list and
message display into that zone.

This should probably be further expanded to get the timezone from the
phone somehow (later TODO).
