Intermittent time-based test failure

[coderkevin]

I've noticed an intermittent time-based test failure, which probably indicates something is getting the "now" time by default assignment instead of being explicitly assigned in the tests. Something to look into:

Scheduler › getNextRequestDelay › returns the same number when a new request that is scheduled later is added

    expect(received).toBe(expected) // Object.is equality

    Expected: 119964
    Received: 119963

      261 | 			const delayAfter = scheduler.getNextRequestDelay( now );
      262 |
    > 263 | 			expect( delayAfter ).toBe( delayBefore );
          | 			                     ^
      264 | 		} );
      265 | 	} );
      266 |
