time_to_xxx() and xxx_to_time() functions. e.g. _time_to_xxx()
instead of time_to_xxx(), to make it more obvious that these are

comes out of committee.
o getopt returns -1 rather than EOF on errors
o getopt returns '?' for characters it doesn't know about, so
don't include them in the getopt options string.
