Crank up log verbosity, it will tell you:

$ ntpd --help
BusyBox v1.31.0 (2019-06-10 12:10:11 CEST) multi-call binary.

Usage: ntpd [-dnqNwl] [-I IFACE] [-S PROG] [-k KEYFILE] [-p [keyno:N:]PEER]...

NTP client/server

    -d    Verbose (may be repeated)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    -n    Do not daemonize
    -q    Quit after clock is set
    -N    Run at high priority
    -w    Do not set time (only query peers), implies -n
    -S PROG    Run PROG after stepping time, stratum change, and every 11 min
    -k FILE    Key file (ntp.keys compatible)
    -p [keyno:NUM:]PEER
        Obtain time from PEER (may be repeated)
        Use key NUM for authentication
    -l    Also run as server on port 123
    -I IFACE Bind server to IFACE, implies -l
