That DT number is the difference between your clock and his. If it were 
off by a second or two, you would see almost all stations off by that 
amount, and in the same direction. If it were off by more than that, you 
would see few decodes at all. 99.9% of my WSJT-X work is on 6M, and I 
rarely see DTs greater than a half second -- most are 0.1 - 0.2. You 
WILL see occasional DTs greater than 1 second.

For many years, I've used this nice little clock utility. Works great.
