There are 2 components to time zone with Unity Connection. The first is the system time zone which is set during install. This is the time seen on the CLI / OS of the box. This is a requirement that both servers be set the same. The second is application time zone (controls the prompts users hear, etc). There is a global setting for application time zone but this can also be modified on a per-user basis. So system-level, same time zone. Application level, time zone can vary based on user.
