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