There are many things that a system admin can get wrong.  Failing
to supply this feature because the sysadmin might not be running
ntpd (or equivalent) correctly seems to me to be like not having
the software do fsync because the sysadmin might not have turned
off write-back buffering on drives without persistent storage.
Either way, poor system management can defeat the feature.  Either
way, I see no reason to withhold the feature from those who manage
their systems in a sane fashion.
