Thanks, pushed to master.

I didn't make parse-iso8601-time-string autoloaded.  I don't think
it's needed; if you think it is, please tell why.

Also, a minor not about log messages:

These are changes in the same function and the same source file.  So
they should be written together, like this:

        * parse-time.el (parse-iso8601-time-string): Fix timezone
        parsing.  Add a doc string.

Thank you for your contribution and for your patience.
