An apparatus which integrates a time control into a detachable power cord. The invention includes an integral power input cord having a power input connector capable of being connected directly to a power source, an integral power output cord having a power output connector capable of being connected directly to an electrical load, a switch for enabling or disabling power to the power output cord, a load status detector for determining whether the electrical load is ON or OFF, a timekeeping mechanism for tracking time-of-day, programmable time limits for restricting usage of the electrical load, non-volatile storage for critical data, secure access to time and program data, and a numeric display and pushbuttons for system interaction. The invention provides inherent security because the timer is integral to the power cord, thus the timer cannot be bypassed. Further, no mechanical locking mechanisms are required to capture a secondary power cord.
