This clock only returns valid timestamps after it received the first
times from the PTP master clock on the network. Once this happens the
GstPtpClock::internal-clock property will become non-NULL. You can
check this with gst.clock.Clock.waitForSync, the GstClock::synced signal and
gst.clock.Clock.isSynced.
Creates a new PTP clock instance that exports the PTP time of the master clock in domain. This clock can be slaved to other clocks as needed.
If gstnet.global.ptpInit was not called before, this will call gstnet.global.ptpInit with default parameters.
