I made a big mistake in #896 by changing the units of various timestamps from nanoseconds -> seconds, which caused QCMP distances to be completely wrong as the unit change caused all calculations to be 0. This fixes the bug by actually having a modicum of type safety so that all conversions between timestamps and duration/nanoseconds are clear as opposed to "losing" the units. It also changes the
qcmp::ping
test to force a delay and ensure that the calculated time is both less than twice the delay but also greater than the delay, which was why this bug was not detected by the test.Resolves: #920
