Pass original int64 response time when caching resource metadata.

Pass original int64 response time when caching resource metadata.

This is part 3/4 of a clean up to switch to int64 time stamps when caching metadata. The background to this is that converting int64 time stamps to double and back to int64 is lossy and causes false time stamp mismatches.
