[ntp:questions] ntp-4.2.6p5 on Win 7 x64

This machine dual boots Mint 17 x64 and Win 7 SP1 x64.

I have set the hardware clock to UTC.

Mint 17 and Win 7 run on local time.

I need reasonable time sync for WSJTX < 1 second.

On Mint 17 ntp from the repo works well with offsets in the low
tens of milliseconds, sometimes < 10ms.

On Win 7 I have installed ntp-4.2.6p5 at spider-man-2-win32-setup.exe.

This does not seem to work properly.

The jitter and offset 'diverge'...

These are not the worst offsets I've seen; 3 seconds is not unusual.

Restarting the service 'fixes' it for a few minutes, then it all begins to
'diverge' again.

Using the default ntp.conf except for "pool uk.pool.ntp.org iburst".

What have I missed?
