Duration Big Bug

[qinfanheaven]

const endTime = dayjs.unix(1716998400).add(32, 'day'); // 2024/7/1/ 00:00:00
const now = dayjs(); // 2024/5/30 13:50:50

const duration = dayjs.duration(endTime.diff(now));

console.log(duration.hours());
// output is "0" which should be "10"
// when change 32 to 30, the hours func returns 10

dayjs 1.11.11

The problem occurs when the difference become 31 days.

const now = dayjs('2024-05-02T01:00:00');


const future30 = now.add(30, 'day');
const duration30 = dayjs.duration(future30.diff(now));
console.log(duration30.hours()); // 🆗 returns 0
console.log('iso', duration30); // "P30D"


const future31 = now.add(31, 'day');
const duration31 = dayjs.duration(future31.diff(now));
console.log(duration31.hours()); // 💥 returns 14
console.log('iso', duration31); // "P1MT14H"
