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.
Famous quotes containing the words precise, time and/or interval:
“The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera—and himself.”
—Daniel J. Boorstin (b. 1914)
“In a time of confusion and rapid change like the present, when terms are continually turning inside out and the names of things hardly keep their meaning from day to day, it’s not possible to write two honest paragraphs without stopping to take crossbearings on every one of the abstractions that were so well ranged in ornate marble niches in the minds of our fathers.”
—John Dos Passos (1896–1970)
“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)
