Add date string to system.out's

I'm trying to add a time date string to all the System.out.println()'s which are being redirected to an output file. The code has tons of system.out.printlns and I'd like to avoid having to change each one to include the date and time.

Any ideas or suggestions, greatly appreciated.

(I'm redirecting with System.setOut(PrintStream) I'm thinking maybe I could extend printstream and add the date and time there but I'm not certain how to go about it)
