FT test steps that rely on dates may fail on different machines, because locales are not locked. Therefore, on different setups there may discrepancies between the browser locale and node's locale, and between these and the format on the step definitions.
To solve this, we need to:
1) agree on a single format to be used henceforth on every step definition
2) either lock the browser locale or allow the test framework to detect the browser's locale
