[K12OSN] DST Changes?

I had a similar problem with a RHEL3 machine. I installed the tzdata
package, and the zdump command shown below worked, but the date still
didn't show right after the DST switch over on sunday.
I found the problem was the /etc/localtime
On some systems its a file that contains timezone info. On other
systems it's a symlink to a file (in my case /usr/share/zoneinfo/EST5EDT).
when you run a command that gets the current time, like the 'date'
command, it looks at /etc/localtime. if that file or link isn't
correct, it'll still report the wrong time.
So, either you need to re-point that symlink at the correct zoneinfo
file, or you need to copy the correct zoneinfo file on top of it.
save a copy of the original file tho. And, there should be no problem
doing this while the system is running.
