This may be bogus, but it is no different than in 4.4BSD-Lite2 and it is specified by POSIX (POSIX.1-200x-draft7: 21836 -c Use time of last modification of the file status information (see <sys/stat.h> in the 21837 System Interfaces volume of IEEE Std 1003.1-200x) instead of last modification of 21838 the file itself for sorting (-t) or writing (-l). 21864 -u Use time of last access (see <sys/stat.h> in the System Interfaces volume of 21865 IEEE Std 1003.1-200x) instead of last modification of the file for sorting (-t) or 21866 writing (-l). The FreeBSD ls clearly attempts to implement this. The FreeBSD man page is clearly a fuzzy version of this: -c Use time when file status was last changed for sorting or print- ing. -u Use time of last access, instead of last modification of the file for sorting (-t) or printing (-l). The FreeBSD man page is missing the critical detail that the status change time and access times are used _instead_ of the modification time. Bruce
