Use Test::Time instead of Time::Mock

From an email:

> All my work laptops are Windows based computers, so I am stuck with
  Activestate or Strawberry perl. I tried to install
  Selenium::Remote:Driver with both cpanm and ppm commands, and both
  fails due to Time::Mock issue. Seems like Time::Mock does not support
  Windows: http://code.activestate.com/ppm/Time-Mock/

> I tried force install commands on cpan, but that didn't work either. I
  am not a professional programmer (I am actually a Pharmacist), so I am
  pretty much stuck right now. Should I try to downgrade a Selenium
  version and try to manually install?

Using Test::Time makes our test faster, significantly less flaky, and it
has excellent test success on Windows:
