Interesting:

Just did an upgrade to 6.2-STABLE from 6.1-RELEASE-p10 and here is  
what I see.

uname -r

6.2-STABLE

zdump -v -c 2008 MST7MDT

MST7MDT  Sun Mar 11 08:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 MST  
isdst=0 gmtoff=-25200
MST7MDT  Sun Mar 11 09:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 MDT  
isdst=1 gmtoff=-21600
MST7MDT  Sun Nov  4 07:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 MDT  
isdst=1 gmtoff=-21600
MST7MDT  Sun Nov  4 08:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 MST  
isdst=0 gmtoff=-25200

Shows the new MST -> MDT and MDT -> MST dates

zdump -v -c 2008 /etc/localtime

/etc/localtime  Sun Apr  1 08:59:59 2007 UTC = Sun Apr  1 01:59:59  
2007 MST isdst=0 gmtoff=-25200
/etc/localtime  Sun Apr  1 09:00:00 2007 UTC = Sun Apr  1 03:00:00  
2007 MDT isdst=1 gmtoff=-21600
/etc/localtime  Sun Oct 28 07:59:59 2007 UTC = Sun Oct 28 01:59:59  
2007 MDT isdst=1 gmtoff=-21600
/etc/localtime  Sun Oct 28 08:00:00 2007 UTC = Sun Oct 28 01:00:00  
2007 MST isdst=0 gmtoff=-25200

Shows the old MST -> MDT and MDT -> MST dates

What did I miss?  What do I do next?
