I did some testing here and found of the 558 available timezones (in JDK 
1.4) that 526 were accepted on 7.4 and 527 were accepted on 8.0, this is 
on an unstable debian box, but it seemed like a pretty good percent.

Well this just kind of reverses the problem, now Java must have the same
set of timezones as the zic database, but I think making TimeZone a 
GUC_REPORT is a good idea because we may want to go that route down the 
line and now we certainly want to detect if someone has manually set the 
TimeZone behind our backs.
