Measure time using Date.now() instead of process.hrtime()

Duration measured in nanoseconds does not give any valuable
information to the developer. It makes sense to display
time only for long-running tests, above some threshold.
Also, process.hrtime() is not available in browsers, so it
would need replacement anyway.
