Utilizing JodaTime with JavaScript (AngularJS): A Comprehensive Guide

I am utilizing DateTime to create Date objects and sending them as JSON to the UI. How can I work with this in JavaScript (specifically AngularJS) and convert it back and forth?

For instance, if I need the user to update the time, I should be able to retrieve the Date/Time from a form submission and send it back to the server in JSON format.

Below is the current DateTime JSON output that the client receives:

"date": {
                "year": 2013,
                "era": 1,
                "dayOfMonth": 3,
                "dayOfWeek": 7,
                "dayOfYear": 34,
                "millisOfDay": 3660000,
                "centuryOfEra": 20,
                "yearOfCentury": 13,
                "monthOfYear": 2,
                "weekOfWeekyear": 5,
                "millisOfSecond": 0,
                "hourOfDay": 1,
                "yearOfEra": 2013,
                "weekyear": 2013,
                "secondOfMinute": 0,
                "secondOfDay": 3660,
                "minuteOfHour": 1,
                "minuteOfDay": 61,
                "zone": {
                    "fixed": true,
                    "id": "UTC"
                },
                "millis": 1359853260000,
                "chronology": {
                    "zone": {
                        "fixed": true,
                        "id": "UTC"
                    }
                },
                "beforeNow": true,
                "afterNow": false,
                "equalNow": false
            }

Answer №1

Taking the question posed by the commenter and transforming it into a concise answer. When displaying the date and time on your server, opt for a simpler timestamp format containing only the milliseconds. Either assume UTC or explicitly include it in the output. The solution to the question has been provided based on the information provided, but there is a suggestion to streamline the message for enhanced clarity.

By utilizing new Date(date.millis);, a JavaScript object displaying the date and time of Sat Feb 02 2013 19:01:00 GMT-0600 (Central Standard Time) is obtained.

In my specific scenario, the timezone is Central.

For questions related to UTC, refer to another post that addresses UTC concerns. To convert UTC Epoch to local date using JavaScript, visit Convert UTC Epoch to local date with JavaScript.

Answer №2

For optimal time storage and display, I highly recommend incorporating ISO 8601. This standard not only includes the date and time like a timestamp, but also includes timezone information. This additional detail is crucial for accurately storing and presenting time data for users in different time zones.
