I was about to answer a different question when I realised what you asked. I don't know the answer to your question. The answer to 'What will the DUT1 offset be after the correction takes place?' is I am not sure. The current offset is -0.3 seconds so it seems suprising that a leap second is due anyway. How do I know? It so happens that the timecode I get from my stratum 1 server tells me: 901207 2027 U -3 660601619.999728 yymmdd hhss Z DUT1 Unix time of the 00 second. Thus my system was out byt 300us (according to this sample).
