Remove humantime dependency

* Use built-in time formatter from chrono library instead of the
  unmaintained `humantime` crate.
* Using the new format method discovered a bug in formatting the time
  when there are no fractional seconds making the width of the output
  not always the same.
* Snapshot test results adjusted after resolving the bug.
