Hello
is there any way build in by unix native commands to show timestamp instead of date when I do "ls -l" ?
if not is there any one liner script to do this?

Do you want to show the time a file was modified instead of the date? Excerpt from the man page of ls

As for a simple one liner, I can give you a simple two liner:

#!/usr/bin/perl -w #-d
$mtime=(stat($ARGV[0]))[9]; @ltime=localtime $mtime; printf "%.4d-%.2d-%.2d-%.2d-%.2d\n",$ltime[5]+1900,$ltime[4]+1,$ltime[3],$ltime[2],$ltime[1];
