after discussing witha professor i have been told that it is possble to use System.CurrentTimeMilliseconds to store the time.
i would like to know how to do this and if it is also possible to show a message if there has been a sudden change of 5 minutes or more
I don't think this is the best option though Dave. The code I gave you in your other thread works exactly as desired.
I'm looking into making it recognise a 5 minute change at the moment..
