I didn't even notice the settings, but that practically guarantees you'll
hit the race condition. Every couple of minutes, it's updating the
timestamp in memory, which means you have a much smaller window to hit. In
other words, don't do this.

I hit this problem with a 15 minute or so window, so you're pretty much
ensuring no updates with that.
