This tells the on-air system at what position to start playing in the current hour. This is helpful when you have created an entire hour in your log shells, but your sign-on time may be at the 1/2 hour mark. You can place the SignOn command half way down your log shell.
SignOn Command
This is what the command will look like as a custom command.
Adding this command all by itself to a command cut and then plugging this command into your shedule will cause this to be the starting point when using the sign-on time in Master Settings. If you do not use this command in your log shells, the DJB will simply start at the begining of the current hour.
