I've made the test with my Pine64, I've disabled the ntpd and set the pine
under heavy load at all cores for a hour. There was no time drift.

You wrote in your previous email, that the problem appear when you set the 
freq to 1200. With higher freq the system consumes more power (not much, but 
more), do you have checked your power adapter, is the 5V stable under high 
load?
