microtime.wasm

WebAssembly implementation of the microtime module.

Note, this module is a proof of concept and likely should not be used. Emscripten implements the C function gettimeofday(2) as a call to JavaScript's Date.now(). This defeats the original purpose of microtime, which was to obtain better than the millisecond accuracy provided by Date.now().

Basic Usage

'use strict';
const { now, nowDouble, nowStruct } = require('microtime.wasm');
 
console.log(now());
console.log(nowDouble());
console.log(nowStruct());

API

microtime.wasm exports the following methods.

now()

• Arguments
  • None.
• Returns
  • result (number) - The current time in microseconds as an integer.

nowDouble()

• Arguments
  • None.
• Returns
  • result (number) - The current time in seconds as a floating point number.

nowStruct()

• Arguments
  • None.
• Returns
  • result (array) - The current time as a two element array. The first element represents the number of seconds. The second element represents the number of microseconds. This matches the return value of gettimeofday(2).
