You have 2 issues: clock skew and GUID states.
The clock skew means that the system clock of your OS / FS aren't in synch. Not necessarily the end of the world but can be nasty when looking at different timestamps in log files for example.
For the second issue: make sure that your GUID refresh has run correctly. It's a topic that's discussed often in here, so check this existing thread: https://community.oracle.com/thread/2538495
