| Behavior when "this" value is an Object without a [[DateValue]] internal slot |
| info: | |
| 1. Let t be LocalTime(? 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. |
