In a new post to the Web Tech blog over on SitePoint, Toby Somerville has posted something he calls "RoughTime" - his method for displaying a more "human friendly" output of a timestamp.

When asked the time, we generally don't need to be military accurate with our response [...] we generally communicate the approximate time. i.e. 'its nearly ten' or 'its just gone half past three'. Yet on the web, time is generally shown as '12:24:13 AM', or similar '" not very visitor friendly.

His RoughTime uses two switch statements to map the hour and minute values to different strings. For example, minutes between 15 and 20 become "quarter past" and the hours are changed over from numeric versions to their word counterparts.
