1. A torque tool adapted to apply torque to a work piece, comprising:

  • a processor;

    a memory operably coupled to the processor;

    a torque sensor operably coupled to the processor;

    a real-time clock operably coupled to the processor;

    a calibration reset switch operably coupled to the processor;

    a calibration timeout indicator operably coupled to the processor, andinstructions stored in the memory, and executable by the processor to;

    receive time data from the real-time clock;

    initiate a time counter based on a reset signal from the calibration reset switch;

    increment the time counter based on the time data; and

    activate the calibration timeout indicator when the time counter reaches a predetermined time count.
