In a while loop we read the input file line by line, and write each line to the output file.
We associate descriptors 3 & 4 rather than the default 0 & 1, so another read/print (for interactive i/o)...

Replace echo with this printf
printf "%02d:%02d" $m $i

You can pass the local script via stdin to the interpreter on the remote host.

@Lucas_0418: It is better to not leave the format argument of printf unspecified. Also if you use [@] instead of

printf "%s\n" "${DATE[@]}"...
