// DATE = 2024-06-13T23:59:59+05:00 let dateTime = dayjs(date, format, locale, strict); // +05 UTC OFFSET dateTime = dateTime.utcOffset(300); console.log(‘1 – ‘, dateTime.format()); // 2024-06-13T23:59:59+05:00 | OK // -03 UTC OFFSET dateTime = dateTime.utcOffset(-180); console.log(‘2 – ‘, dateTime.format()); // 2024-06-13T07:59:59-03:00 | WRONG! SHOULD BE 15:59:59-03:00 Idk why dayjs is converting 2024-06-13T23:59:59+05:00 to 2024-06-13T07:59:59-03:00 timezone dayjs
