What's wrong with the time when Nokia E66 received the SMS and the time of the mobile phone?

Well, the time displayed behind the message is the time when the message passes through the message center! The details of the information are only recorded by your mobile phone. It is the time when you receive the text message! Originally, the time of the mobile phone is a little different from that of the information center, so it takes a little time for the information center to send it to you (the process of sending and receiving short messages is: sender's mobile phone → information center → receiving this mobile phone).
