get_time_code function error

The get_time_code function sometimes delivers the microseconds incorrectly causing the following caption to appear before the previous caption is removed.

I corrected the issue by overriding the function with the code below:

# Format and return a string that contains the converted number of seconds into WebVTT format
def get_time_code( aws_timecode ):
timedelta = datetime.timedelta(seconds=float(aws_timecode))

hours = (timedelta.seconds // 3600) % 24
minutes = (timedelta.seconds // 60) % 60
seconds = timedelta.seconds % 60
microseconds = timedelta.microseconds / 1000
return str( "%02d:%02d:%02d.%03d" % (hours, minutes, seconds, microseconds ))

Start at the get_time_code function and compare its microsecond formatting with the supplied correction. Verify the resulting WebVTT timestamps keep adjacent captions in the correct order.
