When vector processing encounters a goto if service-hours step, it determines if the current day of week and time is within the service hours listed in the corresponding table. This information is used to decide if the goto condition is true or false, and therefore, whether or not to go to the given step or vector. The day of week and time match is based on the system time on the Communication Manager that receives the call. The time used in the calculations is the time the call reaches the goto step.
