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 unlucky hand dealt to clear and precise writers is that people assume they are superficial and so do not go to any trouble in reading them: and the lucky hand dealt to unclear ones is that the reader does go to some trouble and then attributes the pleasure he experiences in his own zeal to them.”
—Friedrich Nietzsche (1844–1900)
“What time of day is it, lad?”
—William Shakespeare (1564–1616)
“The yearning for an afterlife is the opposite of selfish: it is love and praise for the world that we are privileged, in this complex interval of light, to witness and experience.”
—John Updike (b. 1932)
