How can I delete ALL alarms in the stock Clock app? How can I delete ALL alarms in the stock Clock app?

I see that you can delete them one-by-one, but I have 50+ (created regularly with voice commands), and I'd like to get rid of them in one action.
I deleted all alarms in Android Jellybean 4.1.1 by performing the following operations in Settings > Apps > All > Clock:

Force stop
Clear data
Clear cache

YMMV
