ntpdate, which causes large jumps, should only be used at

BEFORE server processes are started, then ntp CLIENT keeps the systems
clock in sync using tiny increments, usually less than a second.
No, ntpd adjusts the clock frequency to keep the system in
close sync with a reliable time source. To work properly,
ntpd expects to be a long-running process so it can figure out
the local clock drift and properly adjust it.
Anyway, drifting off topic here. Bottom line is that your
server needs stable time, which ntpd can provide. Exceptions
are virtual machines, which have their own time tools, and
"personal" devices that sleep/resume frequently, AFAIK no
reliable solution for these.
