- * Tests for Bug 867868 and related Alarm API bugs.
- *
- * NOTE: These tests pass the alarm time to AlarmService as a number and not as
- * a date. See bug 810973 about Date truncating milliseconds. AlarmService does
- * not officially allow a integer, but nor does it disallow it. Of course this
- * test will break if AlarmService adds a type check, hence this note.
- * FIXME: when bug 810973 is fixed.
