#GstReferenceTimestampMeta can be used to attach alternative timestamps and
possibly durations to a #GstBuffer. These are generally not according to
the pipeline clock and could be e.g. the NTP timestamp when the media was
captured.
The reference is stored as a #GstCaps in @reference. Examples of valid
references would be
timestamp/x-drivername-stream: for timestamps that are locally
generated by some driver named drivername when generating the stream,
e.g. based on a frame counter
timestamp/x-ntp, host=pool.ntp.org, port=123: for timestamps based on a
specific NTP server. Note that the host/port parameters might not always
be given.
timestamp/x-ptp, version=IEEE1588-2008, domain=1: for timestamps based
on a given PTP clock.
timestamp/x-unix: for timestamps based on the UNIX epoch according to
the local clock.

Since 1.24 it can be serialized using gst.meta.Meta.serialize and gst.meta.Meta.deserialize.
