      <doc xml:space="preserve">This object implements a custom #GstClock that synchronizes its time
to a remote time provider such as #GstNetTimeProvider.

A new clock is created with gst_net_client_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.

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

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

A #GstNetTimeProvider is created with gst_net_time_provider_new() which

After creating the object, a client clock such as #GstNetClientClock can
query the exposed clock over the network for its values.

The #GstNetTimeProvider typically wraps the clock used by a #GstPipeline.
