Values

Functions and constants included in the Time module.

Time.realTime

realTime : () => Result<Int64, Exception>

Get the current time, in nanoseconds. Time value 0 corresponds with 1970-01-01T00:00:00Z.

Returns:

type	description
`Result<Int64, Exception>`	`Ok(time)` of the current time if successful or `Err(exception)` otherwise

Time.monotonicTime

monotonicTime : () => Result<Int64, Exception>

Get the time of the system’s high-resolution clock, in nanoseconds. This system clock cannot be adjusted and cannot have negative time jumps. The epoch of this clock is undefined, and thus time value 0 is meaningless. Useful for calculation of precise time intervals.

Returns:

type	description
`Result<Int64, Exception>`	`Ok(time)` of the current time if successful or `Err(exception)` otherwise

Time.processCpuTime

processCpuTime : () => Result<Int64, Exception>

Get the number of nanoseconds elapsed since the process began.

Returns:

type	description
`Result<Int64, Exception>`	`Ok(elapsed)` of the elapsed nanoseconds if successful or `Err(exception)` otherwise

Time.threadCpuTime

threadCpuTime : () => Result<Int64, Exception>

Get the number of nanoseconds elapsed since the thread began.

Returns:

type	description
`Result<Int64, Exception>`	`Ok(elapsed)` of the elapsed nanoseconds if successful or `Err(exception)` otherwise
