Redis EXPIRE, SETEX, should detect time overflows

Moving this issue here from Google Code -> http://code.google.com/p/redis/issues/detail?id=660

How to trigger the bug (cut & paste from google code):

pie@reactor ~ % irb irb(main):001:0> Time.now.to_i + 1000 => 1315722345

pie@reactor ~ % redis-cli -p 5011 redis 127.0.0.1:5011> setex foo 1315722345 1 OK redis 127.0.0.1:5011> get foo (nil) redis 127.0.0.1:5011> setex foo 1000 1 OK redis 127.0.0.1:5011> get foo "1"

Using redis 2.2.12 on freebsd 8.2. This is a 32-bit system.
