Can I post “Time scores” to Game Circle on Amazon?

Hideki Matsui

I know how to post time scores to Game Center on App Store.
But, I’m new to Amazon publishing, so I’m not sure how to do it on Amazon.

I want to post Elapsed Time formatted to the hundredth of a second. Game Center on App Store has the format, but Amazon doesn’t have it.

Can I post time scores to Game Circle on Amazon?
Anybody, help me. Thanks!
