Time
Access to system clocks.
Edit on GitHubfrom "wasi/time" include TimeFunctions and constants included in the Time module.
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 |
Result<Int64, Exception>: Ok(time) of the current time if successful or Err(exception) otherwisemonotonicTime : () => 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:

Result<Int64, Exception> | Ok(time) of the current time if successful or Err(exception) otherwise |
Result<Int64, Exception>: Ok(time) of the current time if successful or Err(exception) otherwiseprocessCpuTime : () => Result<Int64, Exception>Get the number of nanoseconds elapsed since the process began.
Returns:

Result<Int64, Exception> | Ok(elapsed) of the elapsed nanoseconds if successful or Err(exception) otherwise |
Result<Int64, Exception>: Ok(elapsed) of the elapsed nanoseconds if successful or Err(exception) otherwisethreadCpuTime : () => Result<Int64, Exception>Get the number of nanoseconds elapsed since the thread began.
Returns:

Result<Int64, Exception> | Ok(elapsed) of the elapsed nanoseconds if successful or Err(exception) otherwise |
Result<Int64, Exception>: Ok(elapsed) of the elapsed nanoseconds if successful or Err(exception) otherwise
