MonotonicTime

@interface MonotonicTime : NSObject

A class to calculate monotinic time from the host’s system clock

  • Frequency of the system clock in ticks per second

    Declaration

    Objective-C

    @property (readonly, nonatomic) Float64 frequency;

    Swift

    var frequency: Float64 { get }

  • A read-only property containing the reference to the system clock

    Declaration

    Objective-C

    @property (readonly, nonatomic) CMClockRef clockref;

    Swift

    var clockref: CMClock! { get }

  • Return current host time in seconds

    Declaration

    Objective-C

    - (Float64)time;

    Swift

    func time() -> Float64

    Return Value

    current host time in seconds (floating point number)

    Swift

    func timeMillis() -> Float64

    Return Value

    current host time in milliseconds

  • Return current host time in microseconds

    Declaration

    Objective-C

    - (Float64)timeMicros;

    Swift

    func timeMicros() -> Float64

    Return Value

    Swift

    func timeNanos() -> UInt64

    Return Value

    current host time in nanos

  • Return this host’s absolute time

    Declaration
