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.
