Sets the expiration time of a key to a Unix milliseconds timestamp.
PEXPIREAT
key unix-time-milliseconds [NX
| XX
| GT
| LT
]
PEXPIREAT
has the same effect and semantic as EXPIREAT
, but the Unix time at which the key will expire is specified in milliseconds instead of seconds.
The PEXPIREAT
command supports a set of options since Redis OSS 7.0:
NX
– Set expiry only when the key has no expiryXX
– Set expiry only when the key has an existing expiryGT
– Set expiry only when the new expiry is greater than current oneLT
– Set expiry only when the new expiry is less than current oneA non-volatile key is treated as an infinite TTL for the purpose of GT
and LT
. The GT
, LT
and NX
options are mutually exclusive.
One of the following:
Integer reply: 1
if the timeout was set.
Integer reply: 0
if the timeout was not set. For example, if the key doesn’t exist, or the operation was skipped due to the provided arguments.
