I do not plan to configure NTP client to sync with the NTP servers for my Solaris servers.
Is it possible that I connect to this NTP servers and sync the time on an ad-hoc basis?

ntpdate command will have the answer of your question.
You could manually sync on an adhoc basis, but based on the simplicity of setting up NTP, you might as well set it up for your servers.
You didn't note your version of Solaris, but the configuration file is going to be similar across the majority of the platforms since most vendors use the same source code for NTP.
Sample simple configuration file for an NTP client below. You'll also usually see vendor samples in that same directory.
server <NTP_SERVER1> prefer server <NTP_SERVER2> peer <NTP_PEER_SERVER1> peer <NTP_PEER_SERVER2> slewalways yes driftfile /var/ntp/ntp.drift statsdir /var/ntp/ntpstats/
