-IdGen also provides an `ITimeSouce` interface; this can be handy for [unittesting](IdGenTests/IdGenTests.cs) purposes or if you want to provide a time-source for the timestamp part of your Id's that is not based on the system time. By default the IdGenerator uses the `DefaultTimeSource` which, internally, uses [`QueryPerformanceCounter`](https://msdn.microsoft.com/en-us/library/windows/desktop/ms644904.aspx). For unittesting we use our own [`MockTimeSource`](IdGenTests/MockTimeSource.cs).

 ```c#
 IdGenerator(int generatorId)
+IdGenerator(int generatorId, DateTimeOffset epoch)
+IdGenerator(int generatorId, DateTimeOffset epoch, MaskConfig maskConfi)
 IdGenerator(int generatorId, ITimeSource timeSource)

 ```
 
 All properties are read-only to prevent changes once an `IdGenerator` has been instantiated.
