What wrote the new values in /etc/init.d/adjtimex?

[Shaul Karl <shaulk@israsrv.net.il>]

[19:42:26 /tmp]$ grep TICK -A2 /etc/init.d/adjtimex 
TICK=10000 # old: TICK=10000
FREQ=-3827584 # old: FREQ=0

--
    /sbin/adjtimex -tick $TICK -frequency $FREQ
    echo "done."
    ;;
[19:42:46 /tmp]$ 

By which process are the new values of TICK and FREQ have been written?
