Provides an interface to get time information from Unity.
For more information, see the following pages in the User Manual: Time and Framerate Management Order of execution for event functions.
| captureDeltaTime | Slows your application’s playback time to allow Unity to save screenshots in between frames. |
| captureFramerate | Time.captureDeltaTime 的倒数。 |
| deltaTime | The interval in seconds from the last frame to the current one (Read Only). |
| fixedDeltaTime | 执行物理和其他固定帧率更新（如 MonoBehaviour 的 FixedUpdate）的时间间隔（以秒为单位）。 |
| fixedTime | The time since the last FixedUpdate started (Read Only). This is the time in seconds since the start of the game. |
| fixedTimeAsDouble | The double precision time since the last FixedUpdate started (Read Only). This is the time in seconds since the start of the game. |
| fixedUnscaledDeltaTime | The timeScale-independent interval in seconds from the last MonoBehaviour.FixedUpdate phase to the current one (Read Only). |
| fixedUnscaledTime | The timeScale-independent time at the beginning of the last MonoBehaviour.FixedUpdate phase (Read Only). This is the time in seconds since the start of the game. |
| fixedUnscaledTimeAsDouble | The double precision timeScale-independent time at the beginning of the last FixedUpdate (Read Only). This is the time in seconds since the start of the game. |
| frameCount | The total number of frames since the start of the game (Read Only). |
| inFixedTimeStep | 如果在固定时间步长回调（如 MonoBehaviour 的 FixedUpdate）内调用，则返回 true，否则返回 false。 |
| maximumDeltaTime | The maximum value of Time.deltaTime in any given frame. This is a time in seconds that limits the increase of Time.time between two frames. |
| maximumParticleDeltaTime | 帧可以在粒子更新上耗用的最长时间。如果帧耗用的时间超过该值，则将更新拆分为多个较小的更新。 |
| realtimeSinceStartup | 游戏开始以来的实际时间（只读）。 |
| realtimeSinceStartupAsDouble | The real time in seconds since the game started (Read Only). Double precision version of realtimeSinceStartup. |
| smoothDeltaTime | 经过平滑处理的 Time.deltaTime（只读）。 |
| time | The time at the beginning of this frame (Read Only). |
| timeAsDouble | The double precision time at the beginning of this frame (Read Only). This is the time in seconds since the start of the game. |
| timeScale | The scale at which time passes. |
| timeSinceLevelLoad | The time since this frame started (Read Only). This is the time in seconds since the last non-additive scene has finished loading. |
| timeSinceLevelLoadAsDouble | The double precision time since this frame started (Read Only). This is the time in seconds since the last non-additive scene has finished loading. |
| unscaledDeltaTime | 从上一帧到当前帧的独立于 timeScale 的时间间隔（以秒为单位）（只读）。 |
| unscaledTime | The timeScale-independent time for this frame (Read Only). This is the time in seconds since the start of the game. |
| unscaledTimeAsDouble | The double precision timeScale-independent time for this frame (Read Only). This is the time in seconds since the start of the game. |
