iburst is fine at restart (of a server), but can mess up drift compensation
of a client that is just switched on (cold system). This is because drift of
a cold system is different from drift of a system that's warmed up.

The difference in drift depends on hardware, but on my (client) machine it
is about 120 when cold, and 177 when at operating temperature. With a quick
sync it actually takes longer for NTP to settle at 177.

I guess for a client there is no need for _quick sync_, but to have *good
time* quickly. ntpdate (or ntp with some option) provides that.
