[ntp:questions] Large variation in NTP synchronization time

Hi all,

I've written a test script to test all the symmetric and autokey
authentication key types and algorithms. The scripts  waits for a delay
time after restarting ntpd and then runs the "ntpq -c as" command to see
if  '*' has appeared beside the server name.The problem is that the
synchronization time varies from about 20 seconds to more than 15 minutes,
even when using -burst and -iburst options for a private ntp server!
What are the minimum, average and maximum synchronization times?
Is there a faster way to verify synchronization?

Thanks

Joe
