To give some context: we have to do some shenanigans to get micro-second precision time on JS and that test verifies that we didn't screw up the math and it works as we expect. Maybe need to make it less sensitive. https://github.com/typelevel/cats-effect/blob/85d6f3c86a345d179589414dfbb5bd33e0432702/core/js/src/main/scala/cats/effect/unsafe/SchedulerCompanionPlatform.scala#L75-L77
