Hi Jim,
Did you look at the below article?

Has anyone ever looked at the timing consistency/behavior of the cheap
RTL-SDR dongles?
That is, if you feed a sine wave in and get the samples out via the USB
interface, are there missing samples? What's the ADC clock look like?
If you had two of them, and you determine the relative phase of them at
some time t0, and you let it run for minutes, how far will it have moved?
