Thank you for the clarification. One question about 'wall clock' time: In the server, my samples come to me timestamped with a REFERENCE_TIME, >> which is an __int64 value with 100 nanosecond units.

So, the sample times I get from my encoder start at 0 and increase (i.e. a relative timestamp); when you say 'wall clock' time, does this mean I should be taking note of the absolute start time? My video source is live, so the timestamps I get from the encoder are (somewhat) arbitrary.
