An unsigned 32-bit integer representing time as the number of seconds elapsed since the Unix epoch (1970-01-01T00:00:00Z) An signed 64-bit integer representing time as the number of seconds elapsed since the Unix epoch (1970-01-01T00:00:00Z); negative for times before the epoch The Text interface is the only user of Unix_Timestamp so far, and we'd like to be Y2038 compatible in future interfaces. A string representing a D-Bus bus name - either a well-known name like "org.freedesktop.Telepathy.MissionControl" or a unique name like ":1.123" A string representing a D-Bus well-known name like "org.freedesktop.Telepathy.MissionControl". A string representing a D-Bus unique name, such as ":1.123" An ASCII string representing a D-Bus interface - two or more elements separated by dots, where each element is a non-empty string of ASCII letters, digits and underscores, not starting with a digit. The maximum total length is 255 characters. For example, "org.freedesktop.DBus.Peer". An ASCII string representing a D-Bus error. This is syntactically the same as a DBus_Interface, but the meaning is different. A string representing a D-Bus signature (the 'g' type isn't used because of poor interoperability, particularly with dbus-glib) A struct (handle, unique name) representing a participant in a D-Bus tube, as returned by GetDBusNames on the Tubes channel type, and as seen in the DBusNamesChanged signal. An ASCII string representing a D-Bus method, signal or property name - a non-empty string of ASCII letters, digits and underscores, not starting with a digit, with a maximum length of 255 characters. For example, "Ping". A string representing the full name of a D-Bus method, signal or property, consisting of a DBus_Interface, followed by a dot, followed by a DBus_Member. For example, "org.freedesktop.DBus.Peer.Ping". A mapping from strings representing D-Bus properties (by their namespaced names) to their values. A D-Bus interface name, followed by a dot and a D-Bus property name. The value of the property. A mapping from strings to variants representing extra key-value pairs. A mapping from strings to strings representing extra key-value pairs.
