There seems to be some disagreement about this point.  CERT, in fact,
notes that explicitly (http://www.cert.org/advisories/CA-2001-23.html).
They also claim that enough infected machines have their clocks set 
wrong that there may be a new outbreak tonight (EDT) -- that one 
strikes me as less plausible.

That hazard isn't specific to August 1.
