Time is relative to ones perception of time and ones movement through time. while you physically have very little you can do in regards to altering your movement in time you can alter your perception of time. Just about any technique you can use to alter your perception of reality can be modified to alter ones perception of time. The capacity is there in the human brain. We do it all the time without even thinking about it. Bore someone enough and an hour becomes an interminable enternity. Take that same hour and alter your perception of it with a more pleasant stimulus and it flies by in what feels like only minutes.
I can't really offer more constructive advice but There's the Invocation of Fotamecus. It works well for long, boring car rides.
