Class Time

A utility class for managing time-related operations and measurements. Provides functionality to track process timing, system uptime, and frame intervals.

Example

// Get current system uptime
const uptime = Time.timeFromSystemStart;

// Get last frame duration
const frameTime = Time.lastTickTimeInterval;

Accessors

StaticintervalProcessBegin

  • get intervalProcessBegin(): number

  • Gets the time interval between the start of consecutive process cycles.

    Returns number

    The interval between process beginnings in seconds

    Remarks

    This value indicates the time gap between when consecutive processing cycles started, which can be useful for measuring frame rate consistency.

StaticlastTickTimeInterval

  • get lastTickTimeInterval(): number

  • Gets the duration of the last completed processing cycle.

    Returns number

    The last tick time interval in seconds

    Remarks

    This value represents the frame time or delta time, which is commonly used for frame-rate independent animations and physics calculations.

StaticlastTimeTimeIntervalInMilliseconds

  • get lastTimeTimeIntervalInMilliseconds(): number

  • Gets the duration of the last completed processing cycle in milliseconds.

    Returns number

    The last tick time interval in milliseconds

    Remarks

    This is the millisecond version of lastTickTimeInterval. Useful when higher precision timing is needed.

StatictimeAtProcessBeginMilliseconds

  • get timeAtProcessBeginMilliseconds(): number

  • Gets the timestamp when the current process cycle began.

    Returns number

    The time in milliseconds when the current process began

StatictimeAtProcessEndMilliseconds

  • get timeAtProcessEndMilliseconds(): number

  • Gets the timestamp when the last process cycle ended.

    Returns number

    The time in milliseconds when the last process ended

StatictimeFromSystemStart

  • get timeFromSystemStart(): number

  • Gets the elapsed time since the system started.

    Returns number

    The elapsed time in seconds since system initialization

    Remarks

    This value represents the total uptime of the system and is useful for animations, timing calculations, and performance measurements.

Methods

Static_processBegin

  • _processBegin(): void
  • Internal

    Marks the beginning of a process cycle and updates timing measurements. This method should be called at the start of each frame or processing cycle.

    Returns void

    Remarks

    This method updates the current process begin time, calculates the interval since the last process began, and initializes the system start time if needed.

Static_processEnd

  • _processEnd(): void
  • Internal

    Marks the end of a process cycle and calculates the processing duration. This method should be called at the end of each frame or processing cycle.

    Returns void

    Remarks

    This method records the process end time and calculates the duration of the current processing cycle (tick time interval).
