Here's a really simple way to do it. Create a script. Just copy any .sqs file and delete whats in it. Then put this in it.
x = the number of hours you want to skip.
titlecut ["","BLACK out",3]
~1
skiptime x
~1
titlecut ["","BLACK IN",3]
exit
Call the file summit like skiptime.
Then put a trigger and in the activation line put,
[] exec "skiptime.sqs"
Done.
Tell me how you get on with it as I just made it up.
