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.
