You'll have to use the gsub() to strip newlines from the output of
"date"...

Sure. One way to do this is to print a formatted version of the special
"NR" variable of awk (NR == number of records read so far):
$ ( echo foo ; echo bar ) | awk '{ printf "%03d %s\n", NR, $0; }'
001 foo
002 bar
$
If you are going to do any amount of *serious* awk programming, I
recommend the following book:

Associates. 2nd edition (March 1997)
