Thanks to a helping hand by Brendon I've made and update to the 1.34 release 
candidate and the CVS head with the new timezone rules for US/Canada (Mexico 
isn't changing).  This file will also work with 1.33.x, so you don't need to 
update your whole install just for the new time zone data.  I've uploaded it 
to the vault/date-time section here:

http://boost-consulting.com/vault/index.php?&direction=0&order=&directory=date_time

I'd appreciate if someone from Indiana could look over the rules for that 
state...not really sure those are 100% yet.

One last note on the use of this file.  As has been discussed previously on 
this list, the library will only give correct answers for current/future date 
conversions now that the rules have changed.  So if you are converting dates 
from earlier years the answers will reflect current time zone rules not past 
rules.  The library doesn't support historic timezone rules presently.

Thx again to Brendon for the assist!
