Yeah, that's surely because of the change to integer timestamps.

This is not the only place where the float-timestamps code has rounding
behavior that doesn't appear in the integer-timestamps code. I don't
know if we want to buy into making them act the same ... after all,
if they acted exactly the same, we'd not have bothered with writing the
integer code. In this example, rounding to hundredths doesn't seem like
a particularly good idea; it seems to me it should give you the exact
down-to-the-microsecond value.
