I'm new at this.
I looked at the TODO list and saw the issue of using comma to delimit
fractional seconds.
I looked at the parser stuff and I think I have at least a start on the
issue.
Is there anything more to it than allowing HH:MM:SS,####### as well as
HH:MM:SS.##### ?
Is it OK if it works that way in all timestamps, not just
ISO-8601-compliant cases?
