Yes, or you could try the documentation:
"ntpdate sets the local date and time by polling the Network Time Protocol
(NTP) server(s) given as the server arguments to determine the correct

obtained from each of the servers specified and a subset of the NTP clock
filter and selection algorithms are applied to select the best of these.
Note that the accuracy and reliability of ntpdate depends on the number
of servers, the number of polls each time it is run and the interval
