- Usage:
-
HPEXPIRETIME key FIELDS numfields field [ field ... ]
- Complexity:
- O(1) for each field, so O(N) for N items when the command is called with multiple fields.
- Since:
- 9.0.0
- ACL Categories:
- @hash, @read, @fast
-
-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.
The HPEXPIRETIME command returns the absolute Unix timestamp (since January 1, 1970) in milliseconds at which the given hash field(s) will expire.
See also the HEXPIRETIME command which returns the same information with seconds resolution.
