I'm using an embedded linux with a startup kernal time of 01/01/2010, with flask hosted site as a config tool. If the device doesn't have an internet connection (to update time from NTP), and they trigger TimeStampSigner.sign() function in itsdangerous.py, the int_to_byte assert fails as num is < 0.

I've not delved into why the logic expects the date to be greater then 2011, but it breaks it for me.

Hi!
I have the same problem. I am using a flask app in an embedded Linux IOT device. Default startup time is 01.01.2000. Do you guys plan to fix this? The only workaround I found is setting date on startup every time.
Another question is why is it exactly 2011?
Thank you!

Update py-itsdangerous to 1.1.0.
Version 1.1.0
-------------

Released 2018-10-26

-   Change default signing algorithm back to SHA-1. (`#113`_)
-   Added a default SHA-512 fallback for users who used the yanked 1.0.0
    release which defaulted to SHA-512. (`#114`_)
-   Add support for fallback algorithms during deserialization to
    support changing the default in the future without breaking existing
    signatures. (`#113`_)
-   Changed capitalization of packages back to lowercase as the change
    in capitalization broke some tooling. (`#113`_)

.. _#113: pallets/itsdangerous#113
.. _#114: pallets/itsdangerous#114


Version 1.0.0
-------------

Released 2018-10-18

YANKED

*Note*: This release was yanked from PyPI because it changed the default
algorithm to SHA-512. This decision was reverted in 1.1.0 and it remains
at SHA1.

-   Drop support for Python 2.6 and 3.3.
-   Refactor code from a single module to a package. Any object in the
    API docs is still importable from the top-level ``itsdangerous``
    name, but other imports will need to be changed. A future release
    will remove many of these compatibility imports. (`#107`_)
-   Optimize how timestamps are serialized and deserialized. (`#13`_)
-   ``base64_decode`` raises ``BadData`` when it is passed invalid data.
    (`#27`_)
-   Ensure value is bytes when signing to avoid a ``TypeError`` on
    Python 3. (`#29`_)
-   Add a ``serializer_kwargs`` argument to ``Serializer``, which is
    passed to ``dumps`` during ``dump_payload``. (`#36`_)
-   More compact JSON dumps for unicode strings. (`#38`_)
-   Use the full timestamp rather than an offset, allowing dates before
    2011. (`#46`_)
-   Detect a ``sep`` character that may show up in the signature itself
    and raise a ``ValueError``. (`#62`_)
-   Use a consistent signature for keyword arguments for
    ``Serializer.load_payload`` in subclasses. (`#74`_, `#75`_)
-   Change default intermediate hash from SHA-1 to SHA-512. (`#80`_)
-   Convert JWS exp header to an int when loading. (`#99`_)
