Laravel 5 Amazon AWS S3 Error: Client error: 403 RequestTimeTooSkewed

I'm trying to upload files to an S3 bucket via a laravel app

I get the following error:

S3Exception in WrappedHttpHandler.php line 152: Error executing "PutObject" on "http://ift.tt/1qvthlM

AWS HTTP error: Client error: 403 RequestTimeTooSkewed (client): The difference between the request time and the current time is too large

I've done some research and many say that my my machine's time is not synced. I'm afraid of messing with homestead because im afraid of breaking something. Do i change my app timezone? Really not sure.

Please help and thank you for taking the time
