file-access-date

Arguments: path

Returns (or sets with setf) the time of last access to the file named by path (which must be a pathname object or a string naming a path). An access is a read or a write of the file. The time is returned as a universal time value. The functions universal-to-unix-time and unix-to-universal-time are useful in converting between universal time (the number of seconds since midnight 1/1/1900) and UNIX time (the number of seconds since midnight 1/1/1970).

This function causes the :osi module to be loaded. See The Operating System Interface (OSI) module in os-interface.htm. Also see file-write-date.
