+This command provides a way to delay,
+by the specified number of broadcast poll intervals,
+believing backward time steps from a broadcast server.
+Broadcast time networks are expected to be trusted.
+In the event a broadcast server's time is stepped backwards,
+there is clear benefit to having the clients notice this change
+as soon as possible.
+Attacks such as replay attacks can happen, however,
+and even though there are a number of protections built in to
+broadcast mode, attempts to perform a replay attack are possible.
+This value defaults to 0, but can be changed
+to any number of poll intervals between 0 and 4.
