Hi,

In ntp.conf modify server line as

server 0.us.pool.ntp.org maxpoll


NTP uses an intricate heuristic algorithm to automatically control the poll interval for maximum accuracy consistent with minimum network overhead. The algorithm measures the incidental offset and jitter to determine the best poll interval. When ntpd starts, the interval is the default minimum 64 s. Under normal conditions when the clock discipline has stabilized, the interval increases in steps to the default maximum 1024 s. In addition, should a server become unreachable after some time, the interval increases in steps to the maximum in order to reduce network overhead

Note:...the user is advised to carefully consider the consequenses of changing the poll adjustment range from the default minimum of 64 s to the default maximum
