Omit the timezone details when initializing a new Date object in Angular

Encountered a problem while testing the following line of code

console.log(JSON.stringify(new Date('2016-06-15 10:59:53.5055')));

The result I'm getting is "2016-06-15T08:59:53.505Z", but I was expecting "2016-06-15T10:59:53.505Z"

Is there a way to strip the timezone information from the new Date?

The issue arises when sending this Date data via an http-post request to an API. The Date gets stringified (incorrectly at the moment)

Answer №1

A solution to adjusting for time zone differences is by calculating the offset and adding it to your date object, as shown in the code snippet below.

var currentDate = new Date('2019-11-20 08:45:30.789');
    var timeZoneOffset = (currentDate.getTimezoneOffset() / 60) * -1; //converting to positive value
    currentDate.setTime(currentDate.getTime() + (timeZoneOffset * 60) * 60 * 1000);
    currentDate.toISOString()

Answer №2

When creating a Date object, it is not possible to remove timezone information due to limitations in the API.

The dates generated using different Date APIs are interpreted based on the specified timezone (if supported by the method), or if not provided, they default to your local machine's timezone; internally, they are represented as dates relative to the UTC timezone.

When you convert a date to a string, it automatically triggers the date.toJSON() method, which then calls date.toISOString(), resulting in a string representation of the time relative to UTC (hence the ending Z denoting Zulu or UTC).

There doesn't seem to be a built-in method that serializes a date to an ISO-like string using the local timezone. If needed, you can utilize low-level Date properties to create a custom serialization method that converts back to the local timezone, or consider using a library like date-fns. Another option is the moment library, known for its versatility, but beware of its size and potential impact on performance.
