Overwriting with SET removes expire time
If SET is run on the same key after expire time is set, expire time is removed and the key is not deleted.
Such commands include set, getset.
Commands such as incr, lpush, sadd, zadd, and hset are not affected.
Example
| Command> | set key value |
| Result> | 1 |
| Command> | expireat key 1534055732 string |
| Result> | 1 |
| Command> | ttl key string |
| Result> | 3 |
| Command> | set key new_value |
| Result> | 1 |
| Command> | ttl key string |
| Result> | -1 |
| Command> | get key |
| Result> | new_value |
