Encountering Random The value X provided for x-amz-pay-date should not be in future

Hello,

I'm using the this dependency for a amazonPay instant checkout option. Every now and then some of the payments fail with this particular error (as mentioned in the title).

I think most of the information needed is there, let me know what else I should provide.

Start by locating where the SDK generates the x-amz-pay-date header for the PATCH checkoutSessions request, then compare that timestamp with the service and host clocks when the failure occurs. The report names no file or test; done should include an established cause, a reproducible check or regression coverage, and confirmation that valid requests no longer send a future date.
