There's a bit of an ambiguity in when that might be, since DUT1 drifts only approximately 300ms every 6 months, there's often two or three choices for dates for a leap second such that DUT1 still remains below 0.9s. Would you try to resolve that at all, or just use whatever published DUT1 numbers to reconstruct an approximation of UT1 and use that for your "GMT" base?
