How do online mapping tools calculate best distance + time?

How do online mapping sites (e.g.: Google Maps, Mapquest, Bing, AAA) calculate best time for routes, and how do their algorithms differ?
I ask because I’ve had slight-to-very different routings (and different time estimates for the same routings) for different sites, and heck, I’m curious.
