Laravel 5.1 Amazon SQS: Getting exception SignatureDoesNotMatch Signature expired

I have configured Queues in Laravel 5.1 using Amazon SQS and it worked fine for the first time but afterwards it is giving following error:

"Error executing \"SendMessage\" on \"queue_url\"; AWS HTTP error: Client error: 403 SignatureDoesNotMatch (client): Signature expired: 20151019T195353Z is now earlier than 20151020T101301Z (20151020T102801Z - 15 min.) - SenderSignatureDoesNotMatchSignature expired: 20151019T195353Z is now earlier than 20151020T101301Z (20151020T102801Z - 15 min.)"

It seems like timestamp associated for the request is being constantly used. How can I configure it in Laravel?
