Coelocanth: Here's something odd: I have two computers networked together. Both are on the same broadband internet connection. On the flash sale countdowns, one computer is showing 2 minutes and 2 seconds faster than the other. (i.e. when the one on the right shows 29:02 remaining for a game, the one on the left shows 27:00 remaining). Same thing with the 'Something special' countdown. Any idea why this is happening? The clock times of each are slightly off. Would that be the issue? I wouldn't think the timer on the site would be synched with the PC clock, would it?
The clocks on your computers are not in synchronization with each other and one or the other or both are probably not using NTP to synchronize with an NTP server over the Internet. Go into your clock settings and make sure "Internet Time" or whatever it is called on your particular OS version is enabled and that the OS can successfully contact the time server without getting blocked by any firewalls on the machine or the router. NTP operates on UDP port 123 in case you need to pop a hole through a firewall.
Once the machines are sync'd with NTP if they were minutes or longer out of time it is sometimes a good idea to reboot because sometimes big clock shifts can cause software to crash or misbehave if it wasn't written to handle clock skew properly and that is often the case in my experience (both as a user and a developer), so I reboot on time changes 30s or greater normally (either direction), it's a little pedantic but avoids issues that can cause me to waste way more time than a reboot takes so I just bite my tongue and go with it :)
After the sync and optional reboot (or at least restart the web browser for sure), try again and in theory the pages should be in sync possibly with minor fraction of a second fluctuations due to in-browser latencies of javascript and whatnot. That should do the trick though.
