ntpdate is a computer program used to quickly synchronize and set computers' date and time by querying a Network Time Protocol (NTP) server. It is available for a wide variety of unix-like operating systems. [1]
The accuracy and reliability of ntpdate entirely depends on the accuracy and network link stability of the first server it connects with.  As this inaccuracy can lead to a multitude of problems, the maintainers have decided to deprecate it in favor of only using the  ntpd  (network time protocol daemon) or a   sntp  (simple network time protocol) query. [2] 
The combination of ntpd and sntp now implements the functions of ntpdate. As soon as a few remaining issues with sntp are resolved the ntpdate program will be retired.
