The reason for this problem is that Amazon S3 allows only a small time stamp variation of up to 15 minutes between the server and its requesting client.

Synchronization of time between the server and the requesting client is very important to have an access to Amazon S3. To get rid of this problem, you have to adjust the client's timing so that there is a maximum time stamp difference of up to 15 minutes. Also set the standard time and zone for your system, in your case set localhost to UTC time.
