Tim-Philipp Müller 64effe78e7 tests: make datetime test more reliably when comparing two almost identical nows
Account for rounding errors in some places, and that two nows are
not always entirely identical, so allow some leeway when comparing
microseconds and seconds. Ran into this too often, esp. when the
system is under load.
