support timestamping of messages. Specifically, timestamping is
only available on the kdbus transport, but not on dbus1. The
timestamping is applied by the kernel and cannot be manipulated by
userspace. By default, message timestamping is not negotiated for

boolean indicating whether to enable or disable the credential
parts encoded in the bit mask value argument. Note that not all
transports support attaching sender credentials to messages, or do
not support all types of sender credential parameters, or might
suppress them under certain circumstances for individual
messages. Specifically, implicit sender credentials on messages
are only fully supported on kdbus transports, and dbus1 only
supports <constant>SD_BUS_CREDS_UNIQUE_NAME</constant>. The sender
credentials are attached by the kernel and cannot be manipulated
by userspace, and are thus suitable for authorization
decisions. By default, only
<constant>SD_BUS_CREDS_WELL_KNOWN_NAMES</constant> and
<constant>SD_BUS_CREDS_UNIQUE_NAME</constant> are enabled. In
fact, these two credential fields are always sent along and cannot
be turned off.</para>
