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