[LEAPSECS] Leap seconds, precision time, and technical progress

2010-12-26 Thread Finkleman, Dave
This old newcomer learns much from these exchanges. I offer the following observation. Technology advances to exploit our ability to realize and measure time precisely increases. Use of spectrum with frequency, time, and code division multiplexing is an example. I realize that the time scale
