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:
“I know if I wake up cold,
and go out into the clear spring night,
still dark and precise with stars,
I will feel the wind coming down hard
like his hand, in fever, on my forehead.”
—Stanley Plumly (b. 1939)
“Mrs. Susan Hart Neville: Oh, Mr. President, it is so good of you to call on me. Wont you please walk into the parlor and sit down?
President Wilson: I havent time to sit down. Your house is on fire.”
—Woodrow Wilson (18561924)
“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 (18171862)
