Cygwin has a conversion routine, which converts the Windows date/time input strings to POSIX-compatible strftime strings for digestion by applicatrions calling nl_langinfo. I just checked: Input: "h:mm:ss tt" Output: "%l:%M:%S %p" This looks pretty much like a 12hour AM?PM format to me. If ls uses what Cygwin provides for the default time format, then it does.
