You should really just use the ms package
A utility function for converting milliseconds into a human readable message.
const { formatMilliseconds, parseMilliseconds } = require('format-ms')
console.log(formatMilliseconds(1000000))
// output: '16m 40s'
console.log(formatMilliseconds(-445500))
// output: '7m 25s 500ms ago'
console.log(formatMilliseconds(961000, { units: 'long' }))
// output: '16 minutes 1 second'
console.log(formatMilliseconds(-445500, { largestOnly: true }))
// output: '7m ago'
console.log(formatMilliseconds(445500, { ignore: [ 'millisecond' ] }))
// output: '7m 25s'
console.log(parseMilliseconds(987654321000))
// output: {
// years: 31,
// weeks: 21,
// days: 0,
// hours: 4,
// minutes: 25,
// seconds: 21,
// milliseconds: 0 }
