Unless you've `zic`ed otherwise, you'll need to use the right zone
name. Else Ruby will fall back to UTC.

[sshaw@localhost trunk]$ TZ="Galaxy/Andromeda" ruby -e'p
Time.now.localtime'
Tue Jan 04 07:48:42 +0000 2011
[sshaw@localhost trunk]$ TZ="Galaxy/Andromeda" ruby -e'p
Time.now.localtime.zone'
"Galaxy/Andromeda"
[sshaw@localhost trunk]$ grep -i galaxy /usr/share/zoneinfo/zone.tab
[sshaw@localhost trunk]$ grep -i 'japan\|tokyo' /usr/share/zoneinfo/
zone.tab
JP	+353916+1394441	Asia/Tokyo
[sshaw@localhost trunk]$ TZ="Asia/Tokyo" ruby -e'p Time.now.localtime'
Tue Jan 04 16:45:55 +0900 2011
[sshaw@localhost trunk]$ strings /usr/share/zoneinfo/Japan | grep -i
jst

[sshaw@localhost trunk]$ TZ="JST-9" ruby -e'p Time.now.localtime'
