creation timestamp

i am on aix5.3

when i touch filename.txt, it shows:

Nov 04 13:47 filename.txt

why it did not show year (2009) ? is it a configure file to activate year ?

IT is not creation it is mtime - modification time. Unix in general has no creation time.
Consider this output from ls -l
-rwxr-xr-x   2 anner   anner1      1915 May  7  2009 uzpaban.shl
-rwxr-xr-x   1 anner   anner1     19372 May  8  2009 UZPMBLP
-rwxr-xr-x   2 anner   anner1      7307 May  8 19:35 uzprsql.shl
-rwxr-xr-x   1 anner   anner1    447988 May 11 06:43 urrmtrx.old

Notice May 8. May 8 is 180 days in the past. I ran this at 12:41 local time, Nov 4.
Any file that is EXACTLY 180 days 00H 00S older than the time you run the ls -l gets
the year added and the time as HH:MI removed.

Any file younger than that gets no year but the time in HH:MI is added in.

This is the default behavior for ls.

Because that's the way ls works. On some systems, you can use "-lT" to force it - check your "man ls" page.

:set number in vi will add line numbers to the file and automatically save to disk.
True or False?
