NTP is a very poor choice for what you want to do. It does not deal
with local time at all, it's UTC all the way.
Have you considered using rdate? See man rdate.
If you are willing to configure your systems properly you can use NTP.
The clock will keep UTC but the systems will display the local time for
the time zone you set. If you have already configured the proper
timezone the clock is actually keeping UTC not local time.
You might find it simpler to use SNTP on the clients.
