I was sending some SMS's today and noticed that the timestamps were not the correct time. Look at the time on my phone and the time on the last SMS. Is this normal? A bug? I ran into another instance where I know they sent me an SMS like 30 minutes before what it said (when I looked at the SMS is said I got it now when I know they sent it 30 minutes ago).

Start paying attention to your timestamps and see if this happens to you.
