ABSTRACT:
According to the present invention, a programmable electronic timing device includes two sets of counter circuits that count minutes, hours, and twelve hour intervals. Both sets of counter circuits feed time data into a time or tide data selector circuit under control of an oscillator circuit to alternately operate a display driver circuit that drives a display means to display real time and then when the next high or low tide is to occur. One of the sets of counter circuits advances the time to the next time that high or low tide is to occur, and, when the high or low tide has been reached, the next high or low tide will be displayed alternately along with the real time.
According to another aspect of the present invention, colored lights indicate whether the tide that is being indicated to occur will be high or low tide.
According to a further aspect of the present invention, additional time will be added when the eighth tide indication takes place to compensate for the fractional times that the previously high or low tides were indicated to have occured.
