MI-L Printing actual time in message window

[Simon Roy]

Hi,
 
            I have a MB application that computes a lot of data.  I have
to run it by night because it will keep my computer busy for too long.
I would like to know how long it takes for the computer to process a
certain amount of data.  I thought about printing the computer clock
time at start and at the end of the process in the message window.  Is
there a way via MB to read the computer clock and put the actual time
into a string variable?
 
Thank you.
 
Simon
