-Internally, this time machine mode is implemented by calling our custom :py:meth:`time_machine_now()`

-Android version support policy
-==============================
-
-Building software for Android always presents a struggle between keeping compatibility with older hardware to save cost
-and utilizing feature of new Android versions to improve functionality, security and stability. To help you plan ahead,
-we are publishing our intended schedule. This is to be understood as a minimum commitment, we will only drop support for
-older versions if there is a technical reason to do so, not because the scheduled time has been reached.
-
-.. warning:: This is a non-binding document. We will try our very best to not to deprecate support for Android versions
-             earlier than listed here, but for technical or economical reasons, it might become necessary to do so under
-             specific circumstances. Specifically, we might be forced to partially drop support for Android versions
-             earlier where we integrate third-party components into our software. Typical examples would be specific
-             payment terminal or printer types where we use a third-party component provided by the hardware vendor.
-
-If we no longer support an Android version, it means that we will no longer publish new versions of the app supporting
-that Android version. This means you are not getting new features or bug fixes, and at some point your app might stop
-working with the pretix server.

-Offering wallet payments (Apple Pay, Google Pay) within the widget
-------------------------------------------------------------------
-
-Some payment providers (such as Stripe) also offer Apple or Google Pay. But in order to use them, the domain of the
-payment needs to be approved first. As of right now, pretix will take care of the domain verification process for you
-automatically, when using Stripe. However, pretix can only validate the domain that is being used for your default,
-"stand-alone" shop (such as https://pretix.eu/demo/democon/ ).
-
-When embedding the widget on your website, the domain of the embedding page will also need to be validated in order to
-be able to use it for wallet payments.
-
-The details might vary from payment provider to payment provider, but generally speaking, it will either involve just
-telling your payment provider the domain name and (for Apple Pay) placing an
-``apple-developer-merchantid-domain-association``-file into the ``.well-known``-directory of your domain.

-Working with Cross-Origin-Embedder-Policy
------------------------------------------
-
-The pretix widget is unfortunately not compatible with ``Cross-Origin-Embedder-Policy: require-corp``. If you include
-the ``crossorigin`` attributes on the ``<script>`` and ``<link>`` tag as shown above, the widget can show a calendar
-or product list, but will not be able to open the checkout process in an iframe. If you also set
-``Cross-Origin-Opener-Policy: same-origin``, the widget can auto-detect that it is running in an isolated enviroment
-and will instead open the checkout process in a new tab.
