PTTL

PTTL key

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.

• The command returns -2 if the key does not exist.
• The command returns -1 if the key exists but has no associated expire.

Return value

Integer reply: TTL in milliseconds, or a negative value in order to signal an error (see the description above).
