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).
Please for the specific semantics of the command refer to the documentation of
EXPIRE.
Background
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:
1if the timeout was set.0ifkeydoes not exist or the timeout could not be set (see:EXPIRE).
@examples
SET mykey "Hello"
EXISTS mykey
EXPIREAT mykey 1293840000
EXISTS mykey
