description: Behavior when "this" value is not an Object
info: |
  1. Let t be ? thisTimeValue(this value).

  The abstract operation thisTimeValue(value) performs the following steps:

  1. If Type(value) is Object and value has a [[DateValue]] internal slot, then
     a. Return value.[[DateValue]].
  2. Throw a TypeError exception.
