Sets the expiration time of a key to a Unix milliseconds timestamp.

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.
