My reading is that they will use Jun and Dec as long as they can keep within a second. Are there any interesting estimates on when that will stop working? How does that compare to the lifetime of a watch or a software package? Tom recently said the decay is 2 ms/day per century. We are interested in 2 sec per year. That's 5.5 ms/year. So only 2 or 3 centuries. I won't be alive, but I'll bet some of our artifacts will still be around. I wonder what software will look like then. > Sounds like the world's first fundamentally flawed "leap second enabled" > watch. Sounds like a good reason to put one in a museum. I wonder if it will still be working when the first bug happens. Will GPS still be transmitting? Will the batteries it needs still be available? (Maybe time to stash a few in the freezer.) -- These are my opinions. I hate spam.
