Hi Charles:
There's another thing the WWVB (& WWV) do that GPS does not and that's Daylight
Saving Time.
Pop quiz. . . . what are the dates DST is turned on and off?

Have Fun,

To be fair to NIST, there really aren't many people using WWVB as a source of laboratory-grade timing signals. As
others have pointed out, it isn't accurate enough for true time nut performance, and to get all of what it *is*
capable of requires heroic efforts. So in truth, the real market for WWVB is not time nuts -- it is people who want
to know the time of day to within a second (the "atomic" clock crowd). And there are LOTS of them. So the change is
likely to provide a modest upgrade path for the vast majority of actual users, at the expense of a few die-hards
(hobbyists, mostly) who are trying to get more out of an LF timing source than it is really capable of delivering.
From a public policy standpoint it seems to make good sense, however much it
may offend time nuts' sensibilities.
Best regards,
Charles
