michael@0:    ECMA Section: 15.9.5.4 Date.prototype.toTimeString()
michael@0:    Description:
michael@0:    This function returns a string value. The contents of the string are
michael@0:    implementation dependent, but are intended to represent the "time"
michael@0:    portion of the Date in the current time zone in a convenient,
michael@0:    human-readable form.   We test the content of the string by checking
michael@0:    that d.toDateString()  +  d.toTimeString()  ==  d.toString()
