shortest DX?

Just checked back over todays reports:-

2008-05-23 11:24 G8EUX 10.140150 -7 0 IO92md +33 1.995 G8EUX IO92md 0 0

anybody say how that was done? I use automatic spot upload. However, I noticed that my PC clock was out this morning - it keeps excellent time mostly, but I think the anti-virus did a download this morning, which may have slowed the clock.
