"Times must be eight digits in HH:MM:SS format"?

[karkusviktor]

This sentence appears twice in the specification in the stop_times.txt section.
Isn't it supposed to be 8 characters? Or 6 digits?
As far as I know the colon is not a digit.

@karkusviktor I think you're right, this is probably a typo and it should read:

Times must be six digits separated by two colons in HH:MM:SS format

...or something similar. From a quick read the GTFS spec doesn't specify a standard for time format, but looking at ISO 8601 it seems to define : as a separator, not a digit.

I'm working on a PR that addresses this issue in addition to a number of other editorial changes. Should be ready for review soon.
