Using moment package, you can easily convert a date string of UTC to a new Date object: const moment = require('moment'); let b = new Date(moment.utc('2014-02-20 00:00:00.000000')); let utc = b.toUTCString(); b.getTime();
Try this: function ExcelDateToJSDate(serial) { var utc_days = Math.floor(serial - 25569); var utc_value = utc_days * 86400; . var date_info = new Date(utc_value * 1000); var fractional_day = serial - Math.floor(serial) + 0.0000001; var total_seconds = Math.floor(86400 * fractional_day);
1 Αυγ 2024 · The Office JavaScript API uses the JavaScript Date object for most of the storage and retrieval of dates and times. The Date object provides methods such as getUTCDate, getUTCHour, getUTCMinutes, and toUTCString, which return the requested date or time value according to Universal Coordinated Time (UTC) time.
24 Αυγ 2023 · Date.UTC() returns a time value as a number instead of creating a Date object. When passed a single number, Date.UTC() interprets it as a year instead of a timestamp. If a parameter is outside of the expected range, the UTC() method updates the other parameters to accommodate the value.
11 Σεπ 2023 · let timeRange = workbook.getActiveWorksheet().getRange("B1"); // Get the current date and time with the JavaScript Date object. let date = new Date(Date.now()); // Add the date string to A1. dateRange.setValue(date.toLocaleDateString()); // Add the time string to B1. timeRange.setValue(date.toLocaleTimeString()); }
Using DateTimeFormat. In basic use without specifying a locale, DateTimeFormat uses the default locale and default options. js. const date = new Date(Date.UTC(2012, 11, 20, 3, 0, 0)); // toLocaleString without arguments depends on the implementation, // the default locale, and the default time zone .
Use the Moment-MSDate plug-in to work with dates. The Moment JavaScript library provides a convenient way to use dates and timestamps. The Moment-MSDate plug-in converts the format of moments into one preferable for Excel. This is the same format the NOW function returns.
