Is there a function with a better name? I'd prefer if it actually said that the
time was in milliseconds.

[nisse-webrtc, 2016/04/19 12:19:25]

There's another pending transition, I think. There's Time32 and Time64, which
both return milliseconds but with different size of the return value. And Time,
which currently is an alias for Time32, with a TODO to change it to Time64.

I could rename Time64 to TimeMs (or add an alias), but I'm not sure that's
appropriate for this cl.

[stefan-webrtc, 2016/04/19 12:40:47]

I'd prefer an int64_t TimeMilliseconds() and maybe also a templated version of
it for the special cases where you want to put the time into for instance the
bitstream. But maybe the int64_t version is enough?

[nisse-webrtc, 2016/04/19 13:48:50]

I think int64_t is enough, no need for templates. I have to check if Time64 is
used anywhere, it's a bit silly with to have to keep that alias.

     if (packet_time.timestamp >= 0)
       arrival_time_ms = (packet_time.timestamp + 500) / 1000;
     size_t payload_size = length - header.headerLength;
