It's an indeterminacy, and a somewhat pernicious one -- I tried to fix 
it a few months ago, and didn't get very far.  My guess is that what's 
happening is inconsistent rounding between two different intrinsic 
functions that both return the current time as a floating-point number, 
or something equivalent to that, but I haven't had any time to poke at 
it farther.
