Alternatively you can customize the variable

+You may find it useful to have Emacs revert files automatically when
+they change. Two minor modes are available to do this. In Global
+Auto-Revert mode, Emacs periodically checks all file buffers and
+reverts any when the corresponding file has changed. The local
+variant, Auto-Revert mode, applies only to buffers in which it was
+activated. Checking the files is done at intervals determined by the
+variable @code{auto-revert-interval}.
