It seems ugly to touch `WordPress.statsLastPingDate` here. How about we make that a private variable, then change `updateCurrentBlogStatsInBackground` to accept a parameter that tells it to always update, ex:

```
public static void updateCurrentBlogStatsInBackground(boolean alwaysUpdate) {
        if (!alwaysUpdate && statsLastPingDate != null) {
            Date now = new Date();
	...
```
