set a key-value pair in redis and expire after 1000 seconds
set test "nnn"
expire test 1000, change the system time to this time tomorrow, using the following command:
ttl test
-2is-2.
excuse me: what is the impact of modifying system time on redis cache?
redis triggers expiration conditions. There are two types:
redis expiration time is the timestamp after the current time + expiration time is settled, that is, the expiration time. Therefore, the change of system time will affect the expiration time of redis.
