Like HTTL this command returns the remaining time to live of hash field(s) that has an associated expiration time, with the sole difference that HTTL returns the amount of remaining time in seconds while HPTTL returns it in milliseconds.

See also the HTTL command that returns the same information with seconds resolution.

Array of values associated with the result of getting the remaining time-to-live of the specific fields, in the same order as they are requested.

• -2: Field does not exist in the provided hash key, or the hash key is empty.
• -1: Field exists in the provided hash key, but has no expiration associated with it.
• Integer: The expiration time associated with the hash key field, in milliseconds.
