How can I put real time from date command while running script

[sukchai]

I used awk command for arrange data.
awk -f script.sh input.file > output.file
#output.file
4549659
5807257
05720
8450405

How can I put real time from date command while running script in front of these data?

try this:
function awkdate() {
cmd = "date + format string"
cmd | getline mydate
if (mydate) {
printf "%s\n", mydate
}
}
