Sure thing. Go to /etc/frameworkd.conf and look at the section
# Subsystem configuration for otimed
# a list of time/zone sources to use or NONE
timesources = GPS,NTP
zonesources = GSM
Just set timesources to NONE and nobody but you will meddle with the
time. Set zonesources to NONE and the same will be true for timezones.

As I said setting timesources to NONE will just not change the time at
all. What isn't implemented, but I'd like to see is a configurable
offset from the current time so people could keep timesources enabled
and still have their clock be 5 minutes early. I don't see any problems
implementation wise, just that someone will have to do it.
