PC time was within seconds of ebays official time ????
I did watch my first few snipes after signing up last year to satisfy my doubts as a newby & they appeared to be in synch (within a few seconds at least).
I tried it again after a week of bids "too late" & "not in time" when it showed up as with a 30 sec lag.
All previous snipes were at least successful in getting a bid in when not already outbid with 7 sec lead.
The last straw for me was a non bid with a 10 sec lead - a winning bid of $335 placed 40 sec before end & my max set to $360. Followed the next day by a non bid with a 15 sec lead & lots of $ to spare...
