Is this user-facing behavior change?

Did you use Generative AI?

Additional Information

see discussion ros2/rclcpp#2910, on the rclcpp layer, this will generate the inconsistent behavior between now and sleep_until methods. until it can be resolved, i think we do not need to merge this rcl layer either.

@ahcorde i think we need to revert this, can you review the description and approve?

Note

after this revert commit is merged, we need to create revert this reverted commit and link it to the client's PRs.

[fujitatomoya]

This type is not checked in the client rclcpp/rclpy layer just yet, that generates the CI warnings.

@ahcorde & @fujitatomoya, I think some tests are still using the reverted API change.

[fujitatomoya]

@SuperJappie08 can you point out where it is in the source code link?

[SuperJappie08]

@fujitatomoya, sorry I looked wrong.
I first tried building without a git-rolling version of rcutiils, and it missed a function, but it was unrelated.
