Hi 2fly1,
In general, parking stats are updated within the hour after they've been collected. Parking statistics are displayed in the Central European Time Zone (CET).
So if the time difference is 6 hours between the eastern United States (EST), the stats shown in the customer accounts relate to US Eastern Standard Time like this:
Sedo stats: November 1, 2007, 00:00:00 (start of day)
US EST: Oct 31, 2007, 6pm
Sedo stats: November 1, 2007, 23:59:59 (end of day)
US EST: November 1, 2007, 05:59:59pm
With regards to parking payments, the value of your keyword is dependent on many things. The length of the keyword, as well as relevancy to your domain name play the biggest parts. Parked pages are also geo-sensitive. If someone is viewing your parked pages in the US, from a US IP address, then the ads should resolve in English as the advertisers in that area would naturally advertise in English.
Conversely, if the domain is viewed in Germany for instance, the ads will be in German with German advertisers. This really works for your advantage, as you will hopefully receive the highest click through rates this way; with the ads resolving being applicable to the users at the specific IP address where the pages are being viewed.
I hope this clarifies! Feel free to PM me if you have any more questions.
