# TTL _key_

> The TTL command returns the remaining time to live in seconds of a key that has an EXPIRE set. This introspection capability allows a Redis client to check how many seconds a given key will continue to be part of the dataset. If the Key does not exists or does not have an associated expire, -1 is returned.
