Well, i think there is no practical way to run a replay script in backgound in the scope of ICEM.

If you just want to let ICEM sleep x hours but not using it, you could write a tcl script which waits that time. Google "tcl sleep after", you should find that the command "after" will let the script sleep the script without returning.

If you want to have a specific time to execute, this approach would likely need a loop to regularly check system time. Again, google this topic with the argument "tcl" since replay scripts are actually tcl scripts.


But again, such approach will only prolong the script's run time. While the delaying script is running, ICEM won't be usable.
