A Time-of-Fight (TOF), with a technique based on plastic
scintillators and finemesh photomultipliers, has been added to the CDF-II
experiment.  The main physics motivation is to improve neutral B meson
flavor determination by K+/- identification.  The expected time resolution
is 100 ps, which provides at least two standard deviations separation
between K+/- and pi+/- for momenta p < 1.6 GeV/c and better than 1.2
standard deviations separation over all momenta when combining TOF
identification with dE/dx identification using the new drift chamber.
