may i know is it possible to synchronize time using ntpdate b/w two

the problem is that our servers are unable to synchronize with our ntp
server as its behind the firewall.
As far as i know, ntpdate uses port 123 UDP to connect to ntp Server
the source port used by the client is choose randomnly >1023.
I am fairly sure that ntpdate, when run with suitable privilege will
source traffic from port 123. ntpd certainly will. So you'd need a
firewall hole with src and dest being UDP/123 between client and
server.
Yes you can use ntpd to sync with a remote ntp server, and that woud
be the normal way of doing it in fact: other than ntpdate (which is
really intended for once-off-use at boot time or what have you), there
is no distinct client-side ntp daemon.
