[dependabot]

Bumps time-machine from 2.15.0 to 2.19.0.

Changelog

Sourced from time-machine's changelog.

2.19.0 (2025-08-19)

• Add marker support to :doc:the pytest plugin <pytest_plugin>. Decorate tests with @pytest.mark.time_machine(<destination>) to set time during a test, affecting function-level fixtures as well.

  Thanks to Javier Buzzi in PR [#499](https://github.com/adamchainz/time-machine/issues/499) <https://github.com/adamchainz/time-machine/pull/499>__.

• Add asynchronous context manager support to time_machine.travel(). You can now use async with time_machine.travel(...): in asynchronous code, per :ref:the documentation <travel-context-manager>.

  PR [#556](https://github.com/adamchainz/time-machine/issues/556) <https://github.com/adamchainz/time-machine/issues/556>__.

• Import date and time functions once in the C extension.

  This should improve speed a little bit, and avoid segmentation faults when the functions have been swapped out, such as when freezegun is in effect. (time-machine still won’t apply if freezegun is in effect.)

  PR [#555](https://github.com/adamchainz/time-machine/issues/555) <https://github.com/adamchainz/time-machine/issues/555>__.

2.18.0 (2025-08-18)

• Update the :ref:migration CLI <migration-cli> to detect unittest classes based on whether they use self.assert* methods like self.assertEqual().

• Fix free-threaded Python warning: RuntimeWarning: The global interpreter lock (GIL) has been enabled... as seen on Python 3.13+.

  Thanks to Javier Buzzi in PR [#531](https://github.com/adamchainz/time-machine/issues/531) <https://github.com/adamchainz/time-machine/pull/531>__.

• Add support to travel() for datetime destinations with tzinfo set to datetime.UTC (datetime.timezone.utc).

  Thanks to Lawrence Law in PR [#502](https://github.com/adamchainz/time-machine/issues/502) <https://github.com/adamchainz/time-machine/pull/502>__.

• Prevent segmentation faults in unlikely scenarios, such as if the time_machine module cannot be imported.

  PR [#543](https://github.com/adamchainz/time-machine/issues/543) <https://github.com/adamchainz/time-machine/pull/543>, PR [#545](https://github.com/adamchainz/time-machine/issues/545) <https://github.com/adamchainz/time-machine/pull/545>.

• Make travel() fully unpatch date and time functions when travel ends. This may fix certain edge cases.

  Issue [#532](https://github.com/adamchainz/time-machine/issues/532) <https://github.com/adamchainz/time-machine/issues/532>__.

2.17.0 (2025-08-05)

• Include wheels for Python 3.14.

  Thanks to Edgar Ramírez Mondragón in PR [#521](https://github.com/adamchainz/time-machine/issues/521) <https://github.com/adamchainz/time-machine/pull/521>__.

• Support free-threaded Python.
