    Description

      Proposed in https://lists.qt-project.org/pipermail/development/2023-May/043971.html thread.

      Ordering timers' timeouts is an orthogonal feature to the coarse timers.

      The fixed implementation of the ordered timeouts inside QtCreator starts here: https://github.com/qt-creator/qt-creator/blob/d56ce22baeebb8ddf79d0c2d04fcf2cc8733defa/src/libs/solutions/tasking/tasktree.cpp#L3135. Each thread orders its timers separately.

      The ordered timeouts might be useful for other Qt users, too.
