use less surprising input for clock option

for the three clock options (no clock, a 12-hour clock, or a 24-hour
clock), use the first character of the option as the input to
fix #2266.

This pull request is a reissue of – and supersession of – #2267,
which was pushed on a branch with non-ASCII characters in the name.
