I uploaded my app yesterday. Its status turned to "Waiting for Review" from "Upload Received" today, but I have also received this e-mail:
We have discovered one or more issues with your recent delivery for "MyAppName". Your delivery was successful, but you may wish to correct the following issues in your next delivery:
Post-dated Code Signature. Code signature identified by 'mybundle.myapp' in bundle 'mybundle.myapp' has a timestamp of '2013-09-04T06:13:09.000-07:00', but it was submitted to the App Store at '2013-09-04T08:48:41.552-07:00'. This might indicate that your system clock is not set to the correct timezone.
If you would like to update your binary for this app, you can reject this binary from the Binary Details page in iTunes Connect. Note that rejecting your binary will remove your app from the review queue and the review process will start over from the beginning when you resubmit your binary.

What does this e-mail mean? Will my app be rejected? Should I re-upload my app?
