Why not just install ntpd and be done? The source code is available for download from ntp.org. If you really want to write your own look at RFC4330 and at the NTP v4 draft now getting ready to become an RFC. Also you need to make sure you keep within the limits of how often you make a request (normally no more frequently than once every 64 seconds) and you need to handle KoD packets and follow the requirements of the draft.
