By definition, a GPS receiver provides you with #2-5 (GPS is fundamentally based on calculations involving time signals, so time readout isn't never optional on any receiver...you always get it). Also, pretty much every GPS receiver will have trip odometer and velocity readouts.
As for mapping, ones that include that function typically only come with basemaps for the US. Other basemaps are optional (re: you gotta pay for 'em), and depending on what area is being mapped, may not be as detailed as maps for the US. For example, maps of Canada may be equally detailed, but don't expect maps of Guatemala or Zimbabwe (just random examples) to provide the same kind of information.
