 `EXPIREAT` was introduced in order to convert relative timeouts to absolute
-timeouts for the AOF persistence mode. Of course, it can be used directly to

+timeouts for the AOF persistence mode.
+Of course, it can be used directly to specify that a given key should expire at
+a given time in the future.
+
+## Options
+
+The `EXPIREAT` command supports a set of options:
+
+* `NX` -- Set expiry only when the key has no expiry
+* `XX` -- Set expiry only when the key has an existing expiry
+* `GT` -- Set expiry only when the new expiry is greater than current one
+* `LT` -- Set expiry only when the new expiry is less than current one
+
+A non-volatile key is treated as an infinite TTL for the purpose of `GT` and `LT`.
+The `GT`, `LT` and `NX` options are mutually exclusive.
