Abstract : The availability of reliable, industrially produced atomic clocks in the mid-1960s brought about a great increase in the use of Precise Time and Time Interval (PTTI) in electronic systems, particularly in communications, electronic navigation, and space systems. By 1968, the need for better planning of timing operations, and also the need to inform systems managers and systems engineers of the capabilities of this new specialization became so great that a special Strategic Planning Meeting was organized at the U.S. Naval Observatory. The original purpose of the meeting, to plan, to exchange practical information, and to bring future requirements into the open, is still with us. The first meeting, in April 1969, demonstrated the need to make it into an annual affair. The talk will summarize the major developments that took place in the last 25 years and we will look back at the contributors and events that are now documented in the Proceedings. The discussion will also include some thoughts about suggested future directions in the organization of these PTTI Strategic Planning Conferences as they have now become a major feature in our timing community.
