LowPoterTimer test gives sometimes failed result while testing measured time accumulation. The check which verifies if total number of elapsed milliseconds is valid fails. Test assumes that delta value equal to 1 ms is sufficient for all test cases, which is not true since in case where time measurement is performed few times in sequence the measurement error also accumulates and 1 ms might be not enough. To solve this problem delta value for milliseconds tests must be updated.
