 You can easily implement your own `TimeProvider` by simply implementing the `ITimeProvider` interface.
 
-As to *why* these Time Providers are implemented: it allows the TwoFactorAuth library to ensure the hosts time is correct (or rather: within a margin). You can use the `ensureCorrectTime()` method to ensure the hosts time is correct. By default this method will compare the hosts time (returned by calling `time()` on the `LocalMachineTimeProvider`) to Google's and convert-unix-time.com's current time. You can pass an array of `ITimeProvider`s and specify the `leniency` (second argument) allowed (default: 5 seconds). The method will throw when the TwoFactorAuth's timeprovider (which can be any `ITimeProvider`, see constructor) differs more than the given amount of seconds from any of the given `ITimeProviders`. We advise to call this method sparingly when relying on 3rd parties (which both the `HttpTimeProvider` and `NTPTimeProvider` do) or, if you need to ensure time is correct on a (very) regular basis to implement an `ITimeProvider` that is more efficient than the 'built-in' ones (like use a GPS signal). The `ensureCorrectTime()` method is mostly to be used to make sure the server is configured correctly.
