The case with this testcase is that the client thresholds are not exceeded and
thus the client thinks that packets were just 0.5 seconds queued on the network
somewhere. It then tries its best to still play those packets and eventually
caches up when the skew correction figures it out.

During the period where the skew algorithm has to adapt, we produce timestamps
that are past the time of the clock (and will thus be late depending on the
downstream latency)

I don't know exactly what to do here. Your patch checks against the current
clock time but that might be suboptimal as it is not known how much downstream
latency there is.
