That makes perfect sense and was the expected behavior. I'm not sure 
what's happening here, but this test code:

Public Sub Main()

   Dim t As Float

   t = CFloat(Now) ' Current time and date.

   Print "1: CDate(t):                         " & CDate(t)
   Print "2: Format$(CDate(t), \"hh:nn:AM/PM\"): " & Format$(CDate(t), 
"hh:nn:AM/PM")
   Print "3: CDate(t):                         " & CDate(t)
   Print "4: Format$(CDate(t), \"hh:nn:AM/PM\"): " & Format$(CDate(t), 
"hh:nn:AM/PM")
   Print "5: CDate(t):                         " & CDate(t)

End

Produces these results:

1: CDate(t):                         06/25/2011 18:35:46.837
2: Format$(CDate(t), "hh:nn:AM/PM"): 06:35:PM
3: CDate(t):                         06/25/2011 06:35:46.837
4: Format$(CDate(t), "hh:nn:AM/PM"): 06:35:AM
5: CDate(t):                         06/25/2011 06:35:46.837

I checked, and the value of variable "t" is not being changed. However, 
after the first Format$, CDate(t) returns a different value than before 
the first Format$. Any idea why? Lines 1 and 2 look good, but it seems 
like lines 1 and 3 should print the same value. Somehow the Format$ line 
continues to have an effect on the subsequent lines.

I hope I'm really not so stupid that I'm missing something obvious. I'm 
not even drinking right now!
