to a remote time provider such as #GstNetTimeProvider. #GstNtpClock
implements a #GstClock that synchronizes its time to a remote NTPv4 server.

A new clock is created with gst_net_client_clock_new() or
gst_ntp_clock_new(), which takes the address and port of the remote time
provider along with a name and an initial time.

This clock will poll the time provider and will update its calibration
parameters based on the local and remote observations.

The "round-trip" property limits the maximum round trip packets can take.

Various parameters of the clock can be configured with the parent #GstClock
"timeout", "window-size" and "window-threshold" object properties.

A #GstNetClientClock and #GstNtpClock is typically set on a #GstPipeline with
gst_pipeline_use_clock().

If you set a #GstBus on the clock via the "bus" object property, it will
send @GST_MESSAGE_ELEMENT messages with an attached #GstStructure containing
statistics about clock accuracy and network traffic.</doc>

           line="20">GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in slave-only
mode, that allows a GStreamer pipeline to synchronize to a PTP network
clock in some specific domain.

The PTP subsystem can be initialized with gst_ptp_init(), which then starts
a helper process to do the actual communication via the PTP ports. This is
required as PTP listens on ports &lt; 1024 and thus requires special
privileges. Once this helper process is started, the main process will
synchronize to all PTP domains that are detected on the selected
interfaces.

gst_ptp_clock_new() then allows to create a GstClock that provides the PTP
time from a master clock inside a specific PTP domain. This clock will only
return valid timestamps once the timestamps in the PTP domain are known. To
check this, you can use gst_clock_wait_for_sync(), the GstClock::synced
signal and gst_clock_is_synced().

To gather statistics about the PTP clock synchronization,
gst_ptp_statistics_callback_add() can be used. This gives the application
the possibility to collect all kinds of statistics from the clock
synchronization.</doc>

clock in @domain. This clock can be slaved to other clocks as needed.

If gst_ptp_init() was not called before, this will call gst_ptp_init() with
default parameters.

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_wait_for_sync(), the GstClock::synced signal and
gst_clock_is_synced().</doc>
