EXPIREAT
has the same effect and semantic as EXPIRE
, but instead of specifying the number of seconds representing the TTL (time to live), it takes an absolute Unix timestamp (seconds since January 1, 1970). A timestamp in the past will delete the key immediately.
Please for the specific semantics of the command refer to the documentation of EXPIRE
.
EXPIREAT
was introduced in order to convert relative timeouts to absolute timeouts for the AOF persistence mode. Of course, it can be used directly to specify that a given key should expire at a given time in the future.
@return
@integer-reply, specifically:
1
if the timeout was set.0
if key
does not exist.@examples
SET mykey "Hello"
EXISTS mykey
EXPIREAT mykey 1293840000
EXISTS mykey
