A deadline time that is too close to the system clock should return a different gRPC status code so that callers of gRPC calls can know that InvalidArgument is non-retryable for repeated forms of the same input.
If a poll request is made with a deadline time within 2s of the server system clock, an InvalidArgument is returned. This only happens when there is a proxy that would hold up a request during internal server outage (very rare). This behavior has existed for years.
Arguably we should stop considering InvalidArgument non-retryable on the SDK side which may make this need moot (see https://github.com/temporalio/features/issues/218). This is simply to track potential work/discussion.
