As requested, here is a tzconfig varient that uses debconf for its UI. A
sample run (note that new installers will be seeing the dialog frontend
instead):

Time Zone Configuration
-----------------------
Your current time zone is set to US/Eastern.
Do you want to change your current time zone? y
Pick the geographic area in which you live.
1. Africa 5. Asia 9. Indian Ocean
2. America 6. Atlantic Ocean 10. Pacific Ocean
3. US time zones 7. Australia 11. System V style time zones
4. Canada time zones 8. Europe 12. None of the above
What area do you live in? US
Cities represent the time zone in which they are located, so you may choose any
city in your time zone.
1. Alaska 4. Central 7. Hawaii 10. Mountain
2. Aleutian 5. East-Indiana 8. Indiana-Starke 11. Pacific
3. Arizona 6. Eastern 9. Michigan 12. Samoa
Select a city or time zone: eastern
Time zone selected.
Local time is now: Sun Jun 10 17:22:34 PDT 2001
Universal Time is now: Mon Jun 11 00:22:34 UTC 2001
You selected the time zone: US/Pacific

If you want to try it, you should probably install debconf 0.9.63 from
Incoming. It tickles an obscure debconf bug fixed by that version.
I have not figured out where this program should live. It'd be sorta cool
if it could replace the current tzconfig, though libc6 would need to
suggest/reccommend debconf then. Or I can stick it in base-config for the
time being.
