Plugin: Google Analytics for Dashboard error – Timestamp is too far from current time

Has anyone used the Google Analytics for Dashboard plugin?

I’ve installed it successfully, but whenever I try to link it to my Google Account using the Start Login Process button, I keep getting a weird message that goes like:

Timestamp is too far from current time: <a Unix timestamp here>

I’m using WordPress 3.1.3.

Any ideas what’s happening here?

Thanks,
