Programmatically trigger timing database save/sync?

When Grindstone exits (because of a reboot, for example), I lose timing data since the last database sync. Usually just a couple minutes, but I’m hoping to avoid that.

Is there any way to externally programmatically “force” Grindstone to sync its data without going the Menu > Exit route? I don’t always remember to exit, but I can make the computer “remember”.
