You could stop ntpd, and then use the adjtimex program to set the
clock rate to a slower value, so that the systems will lose time.
(using the --tick option)
Calculate how long it is going to take to arrive at the correct time
using the setting you decide on, and then come back to the system
(probably put an alert in your electronic calender) to check that the
time is slightly behind correct time.
Then reset the adjtimex setting to the normal rate and restart ntpd.
It will probably jump forward a little at that moment but that should
not matter.
