timestamp for output?

Hi All

If a run a program directly, I can see the output sometimes fast sometimes slow and I know which part is spending more time. However, running a test inside jtreg prints the output all at once after the test completes. Is there an option so that I can add a timestamp to each line no matter if it's STDOUT or STDERR?
