ntpdate

When I run ntpdate, my system clock displays the time as an hour behind what it should be. I know that ntpdate does everything in UTC, so I'm guessing there's a timezone setting wrong and it's ignoring Daylight Savings Time, but I can't figure it out.

Here's what I've done so far:

ln -sf /usr/share/zoneinfo/EST /etc/localtime to set the timezone
Set UTC=true in /etc/sysconfig/clock so that DST will be automatically applied
date -s hh:mm::ss to set system clock correctly
hwclock -systohc --utc to set the hardware clock correctly

At this point date and hwclock both display the correct time.

But if I then run ntpdate 0.us.pool.ntp.org, the date output is an hour behind what it should be.

I've looked at a dozen tutorials and can't figure out what I'm doing wrong. Does anyone have any ideas?

Hi I was wondering if there is any jquery function around which can take this dateTime "2010-10-18 10:06" and convert and split it returning "2010/10/18" and "10:06".
