В моих аналоговых часах C# Winforms Как исправить линию секунды, сделав первое время назад, а затем продолжить вперед пр ⇐ C#

[Anonymous]

Это происходит, когда я меняю состояние флажкового ящика на режим прыжков, затем линии секунды впервые сделают один шаг назад, затем продолжаю прыгать каждую секунду вперед, как и должно быть. Затем, если я переключаюсь больше раз между режимом прыжка и плавным режимом, когда я переключаюсь в режим прыжка, иногда существует небольшой обратный шаг, то он продолжает вперед. Таким образом, один большой один раз назад шаг после запуска приложения и перехода на режим прыжка, а иногда и небольшой, но также один обратный прыжок при снова переключающемся между состояниями.
