Time Zones:

I've handled this two ways.  The first is to set the server itself for
your current time zone.  In one of your startup files, insert the
following line:

EXPORT TZ=EST5EDT

The other way is to set your server to reflect universal standard time,
but for each user, have in their .config file EXPORT TZ=EST5EDT.

I normally use the latter.  Keeps things straight 24/7.

Time Servers:

Download the xntpd package.  As you are using Redhat, this should be
fairly easy in that it is a prebuilt RPM.  I normally run Slackware, so
I end up compiling.  Either way is not a problem.  In the archive is a
listing of first and second stratum time servers that you can synch
from.  I normally use a second stratum server with fine results.

Let me know if you need some additional assistance.
