Opening Address

摘要

It is my pleasure to open this, the Thirty-first Annual Precise Time and Time Interval Meeting. This series of PTTI Meetings has continued to serve the timing community and provide an opportuntiy for users to bring foerward their ideas, thus allowing time and time interval providers to make the system developers aware of their latest improvements in the field and the direction research is heading. Our objectives-to disseminate and coordinate PTTI information at the user level, to review present and future PTTI requirements, to inform Government engineers,technicians and managers of precise time and frequency technology, and to provide an opportunity for an active exchange of new ideas associated with PTTI-are more important today than ever before.
