    Timer

    supertom44
      Hi all, I am currently working on an International Space Station project and I want a timer that shows how long the space station has been in orbit, like the one located on the nasa website.

      The only problem is Im not too sure how to go about it. I know I can get the system date, but I dont know how to work out the difference between a system date and a given date ie the launch date of the iss.

      Can anyone help me out?

      Cheer.
