Precise Time and Time Interval

Precise Time and Time Interval is a Department of Defense Military Standard which details a mechanism and waveform for distributing highly accurate timing information.

It is similar to Pulse per second (PPS) because it indicates the start of each second using a pulse. PTTI also provides the full Time Of Day (TOD) in hours, minutes, and seconds.

    A modern proverb along the lines of “don’t count your chickens before they’re hatched.” This form of words has no precise origin, though both Bartlett’s Familiar Quotations (16th ed., 1992)

    What a devil hast thou to do with the time of the day? Unless hours were cups of sack, and minutes capons, and clocks the
    tongues of bawds, and dials the signs of leaping-houses, and the blessed sun himself a fair hot wench in flame-colored
    taffeta, I see no reason why thou shouldst be so superfluous
    to demand the time of the day.
    William Shakespeare (1564–1616)

    I was interested to see how a pioneer lived on this side of the country. His life is in some respects more adventurous than that of his brother in the West; for he contends with winter as well as the wilderness, and there is a greater interval of time at least between him and the army which is to follow. Here immigration is a tide which may ebb when it has swept away the pines; there it is not a tide, but an inundation, and roads and other improvements come steadily rushing after.
    Henry David Thoreau (1817–1862)
