我有这个功能
const performance = require('perf_hooks');
var t0 = performance.now();
setInterval(printStatus, 20000);
function printStatus() {
console.log(
`Total records: ${count}`
);
console.log("Time elapsed" + (performance.now() - t0)/60000 + "minutes")
}
这将打印如下所示的分钟:Time Elapsed0.3334145895500978分钟
我想让它变成人类可读的，HH:MM:S我怎么做到？
我会这样做:
const performance = require('perf_hooks');
var t0 = performance.now();
setInterval(printStatus, 20000);
function printStatus() {
console.log(
`Total records: ${count}`
);
const msElapsed = (performance.now() - t0);
const hhmmss = (new Date(msElapsed)).toISOString().substr(11,8);
console.log("Time elapsed " + hhmmss )
}
