 <Note>
-  There is a security threshold of one minute on GTD expiration. To set an
-  effective lifetime of N seconds, use `now + 60 + N`. For example, for a
-  30-second effective lifetime, set the expiration to `now + 60 + 30`.
+  GTD orders expire one minute before their stated expiration as a security
+  threshold. To set an effective lifetime of N seconds, use `now + 60 + N`.
+  In addition, the expiration must be at least three minutes in the future —
+  orders expiring sooner are rejected — so the minimum effective lifetime is
+  about two minutes.
