Hello Stephen,
Thank you for your message. Our records indicate that last year you won several auctions and later disputed two charges as fraud, which resulted in service fees on our end. As a result, eBay has revoked any further permission for you to use our service, and we are unable to transact with your account.
Regarding the timing question: our system clock is synchronized with eBay’s to within approximately 1 millisecond. Accuracy cannot meaningfully exceed this in practice. The on-screen display refreshes every 5 seconds by design to maintain browser performance.
I hope this has been explained to your satisfaction. Thank you for writing in, and please let me know if you have any other questions.
