Transforming a JavaScript Date object to a Java LocalDateTime

In my current project, I am facing a challenge while attempting to pass UTC time from a JavaScript front end to a Java backend. My initial approach involved utilizing the Date.toISOString() method and sending the generated object to the Java backend. However, I encountered an issue where the output format of toISOString() (YYYY-MM-DDTHH:mm:ss.sssZ) does not align with any of the predefined formatters for LocalDateTime in Java 8.

Asking for recommendations or best practices, I am wondering if there exists a standardized method for achieving this task. While I acknowledge that creating a custom Java formatter to match the JavaScript output is a viable solution, I am curious if there is a commonly accepted practice due to the frequency of scenarios like mine in development projects.

Answer №1

When working with dates in your code, it's important to know that there are default ISO date formatters available for use.

To parse a string into a LocalDateTime object using the ISO_DATE_TIME format, you can do the following:

Keep in mind that this method will assume the time zone of UTC for the resulting LocalDateTime object.

Update: In response to feedback from Andreas,

If you need the instance of LocalDateTime to be in the server's timezone instead, you can achieve this by using the following code snippet:

LocalDateTime.ofInstant(Instant.parse(str), ZoneId.systemDefault())
