ECJ by default has a fixed seed.  But if you're using one thread (the  
default), just add the parameter:

seed.0 = time

If you're using additional threads, you need to add seed.1, seed.2,  
etc. as well

You can include this in your parameter file, or you can say something  

	java ec.Evolve -file myFile.params -p seed.0=time
