| 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() |
