i think ur right, but even when u do succeed, lets take a more byzantine
approach: what if the time service is down? sabotaged? damaged? maybe it
lies through its teeth(ports) ?? maybe ur vector time is corrupted? maybe
a user deliberately changed his vector time - he will bring havoc upon
ur system .

so, srfs takes the approach of 'trust no one, not even myself' .
a bit paranoid, but very useful (although the cost is very high... )
