The current specification for the '%p' flag in "[tab:time.parse.spec]
parse flags" places a restriction of it's
placement with regards to the '%I' command:
The locale's equivalent of the AM/PM designations associated with a 12-hour clock. The command %I must precede %p in the format string.
This restriction makes the migration to new API more difficult, as it is not present for the POSIX strptime nor in the example implementation of the library. Per Howard's comment:
Actually this is an obsolete requirement and it should be struck. The first time I implemented this I didn't know how to do it without this requirement. I've since reimplemented it without needing this.
