Here is an excerpt from the patent on Zyklon:

   Wenn man den Inhalt der Buechse in duenner Schicht ueberstreut,
   verdunstet die Blausaeure in etwa 10 Minuten, so dass die
   Hoechstkonzentration des Gases im Raume mit ausserordentlicher
   Schnellighkeit erreicht wird.

meaning

   The prussic acid will evaporate in appr. 10 min. if the contents
   of the can is strewn in a thin layer, so the maximum concentration
   of the gas in the room will be achieved with extraordinary speed.

However, the grain size of the absorbent (diatomite) isn't defined in
the patent, so this is certainly no proof in itself that such a short
time would apply to the gas chambers.  This is a ballpark, but more
research is needed.
