It is wrong to suggest that the clock of an IP webcam has any relation at all to the PC clock both absolute or relative. The best course of action is to generalize what was done with v4l: make > it an option. > This is as usual a major flaw in v4l2. The monotonic clock should always be used. It's the least-worst clock.
