I am writing a UNIX system program to retrieve file information using the stat system call. In my code I have the following lines: struct stat statbuf; stat (filename,&statbuf); printf ("%ld",statbuf.st_mtime); This prints out a number like 661742557 for the time the contents of the file were last modified. What does this number mean and how would I convert to more intelligible format (such as day/month/year hour:minute) if possible ? Any comments would be much appreciated.

This is the number of seconds since 00:00:00 GMT Jan 1 1970. To convert it to something `meaningful', such as the ASCII string in my previous sentence, use ctime(3). -- ======================================================================= "Pro is to con, as progress is to Congress..." >>-@@-> Dave Jenks {uunet | ucbvax!ucdavis}!csusac!jetfuel =======================================================================
