2.1.107 [ECMA-262-1999] Section 15.9.5.4, Date.prototype.toTimeString ()
V0167:
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.
For JScript 5.x running on Windows, the string is determined as follows:
Let tv be this time value.
If tv is NaN, return the string "NaN".
Let t be LocalTime(tv).
Using t, create a string value with the following format, based upon the format description given in [ECMA-262-1999] Section 15.9.5.3. The format is: hh:mm:ssbzzzzzz.
Return Result(4).
