you'll probably have to convert time to something more tangible, do ur maths, then convert ur strings back

like convert it all to seconds, add, do ur maths, then feed ur seconds back into one of the time strings

so like take current date and old date and convert both to seconds, do maths, then convert seconds back to days/hrs/months etc back to something more human readable

ONE of those functions may or may not do that for u, or part of it, u got to dig around in the documentations
