Atomic bombs? Really? That's your new argument? Not too long for Godwin, now...
...however, if we're now playing "Where's Teller?", try looking in a mirror. Stunningly blind technological suggestions are a tenth Krone a dozen.

Steve's point was clear. Clock adjustments were more frequent in the past; evidence that the CCIR recognized that atomic frequency standards and universal time clocks are two different phenomena.
Tom's point was clear. More frequent implies a smaller amplitude; timekeeping devices have improved.
The ITU's point is clear: "never" and "infinite amplitude". It is also clear that many of us don't consider this a reasonable way to dig the next Panama Canal of precision timekeeping.
Your point is clear. Delay public discussion until the result is moot.
