Like TTL this command returns the remaining time to live of a key that has an expire set, with the sole difference that TTL returns the amount of remaining time in seconds while PTTL returns it in milliseconds.
Integer reply: TTL in milliseconds, or a negative value in order to signal an error:
- -2 if the key does not exist.
- -1 if the key exists but has no associated expire.
> SET mykey "Hello"
OK
> EXPIRE mykey 1
(integer) 1
> PTTL mykey
(integer) 999
