[ntp:questions] Synchronizing to LOCAL(0): Startup time

"prefer" should only be used against one peer/server. This tells NTP that
all things being equal, choose this one over the others. Not only do you
list it in multiple peers, but also multiple times in the same line.

"iburst" tells it to send multiple packets when it is unsynchronized, which
helps speed up the initial synchronization. "burst" on the other hand tells
it to send multiple packets when it is synchronized. IIRC it is not
recommended to use burst (except for specific cases).

You don't really need iburst for your local clock.

"minpoll 4" tells it poll every 16 seconds. That plus "iburst" should get
you roughly synched up in a couple minutes instead of the usual 15-20.

Don't expect to be synced in just "a couple seconds", it takes more time
than that to build up data. If you just want a one-shot initial
synchronization then use 'ntpdate'.
