+## Notes for boot2docker
+
+It [appears](https://github.com/boot2docker/boot2docker/issues/290) that boot2docker (OS X, Windows) currently does not automatically sync the system clock with the host system after a host resumes from sleep. This becomes a problem due to the way nodemon detects file changes. That might cause it to go bananas, if the clocks on both systems are "too much" out of sync. Until this is fixed, you might use [this workaround](https://github.com/boot2docker/boot2docker/issues/290#issuecomment-62384209) or simply do a manual sync via
+
+```bash
+/usr/local/bin/boot2docker ssh sudo ntpclient -s -h pool.ntp.org
