And it would. The rounding error for this particular argument is more acute than most in the 10-digit HP41 environment. The 12-digit HP42S (I assume you mean the real calculator) gives a couple of more digits so the rounding issues would be in the 11th and 12th place as opposed to 9th and 10th. Moreover, for that particular argument even with adequate precision available GMST is only going to give 10 or 11 correct digits anyway.
