Simply put, using the `to_realtime` method for low and higher frame rates on a "00:00:00:00" timecode produces the following inconsistent results: ``` >>> Timecode(24, "00:00:00:00").to_realtime(as_float=False) '00:00:00.042' >>> Timecode(48000, "00:00:00:00").to_realtime(as_float=False) '00:00:00.000'...
