It works for me well, e.g. Raspbian Buster:

--- clip clip ---

tauno@raspberrypi:~ $ ntpq
ntpq> rv
associd=0 status=0615 leap_none, sync_ntp, 1 event, clock_sync,
version="ntpd 4.2.8p12@1.3728-o (1)", processor="armv6l",
system="Linux/4.19.57+", leap=00, stratum=4, precision=-18,
rootdelay=9.594, rootdisp=72.311, refid=192.89.123.26,
reftime=e0ed8320.90ce5300  Thu, Aug  1 2019 18:26:24.565,
clock=e0ed893d.80bb5410  Thu, Aug  1 2019 18:52:29.502, peer=48597,
tc=10, mintc=3, offset=0.077807, frequency=-31.036, sys_jitter=1.253593,

ntpq> q

You asked how to poll the state of NTP, and ntpq is
a tool from the original developer of NTP,
Prof David L. Mills, see .
