For all those folks running Cisco CallManager Express your life is relatively easy to do the Daylight Saving Time correction required. All you have to do on your router is:
clock summer-time PDT recurring 2 sun mar 02:00 1 sun nov 02:00
of course, this is assuming you are on Pacific Standard Time and you already have configured:
clock timezone PST -8
It is useful if you are using a public NTP site (with permission) to get UTC so you have an accurate time source. Take a look at:
http://www.eecis.udel.edu/~mills/ntp/clock2a.html
It is a list of NTP servers that are stratum 2 and it lists the acceptable use requirements also.
Oh, if you have newer IOS releases don't be surprised to see the command revert back to:
clock summer-time PDT recurring
Seems that Cisco made the adjustment in 12.4(9)T or so - you can get the details at cisco's website

Please please PLEASE refer people to one of the NTP pool servers instead of referring them to a NTP root server. The root servers are heavily taxed as they are already.

Thank you very much.
