/**
 * We extend `Date` during builds and revalidates to ensure that prerenders don't observe the clock as a source of IO
 * When cacheComponents is enabled. The current time is a form of IO even though it resolves synchronously. When cacheComponents is
 * enabled we need to ensure that clock time is excluded from prerenders unless it is cached.
 *
 * There is tension here because time is used for both output and introspection. While arbitrary we intend to reserve
 * `Date` for output use cases and `performance` for introspection use cases. If you want to measure
 * how long something takes use `performance.timeOrigin` and `performance.now()` rather than `Date.now()` for instance.
 *
 * The extensions here never error nor alter the underlying Date objects, strings, and numbers created and thus should be transparent to callers.
