Why I obtain an “Invalid Date” error when I try to set a Date object into a JS script performed in Rhino?

Question

I am not so into JavaScript and I have a huge problem trying to perform a simple JavaScript code into Rhino ( https://developer.mozilla.org/it/docs/Rhino ) that is a JavaScript implementation that allows to perform JS code into a Java application. In my specific case Rhino is embedded into WSO2 ESB (an ESB tool developed in Java).

I can perform my JS code into my Java\\WSO2 ESB application but I am experiencing some problem trying to create a JavaScript Date object. In this case it can't work.

If in my JS code I have something like:

var dateCurrentOriginalForecast = new Date('2017-11-09 06:00:00');

it works fine if I perfom it into the browser but performing it into Rhino I obtain the following error message into the Java console:

TID: [-1234] [] [2017-11-09 15:55:43,610]  INFO {org.apache.synapse.mediators.bsf.ScriptMessageContext} -  dateCurrentOriginalForecast: Invalid Date {org.apache.synapse.mediators.bsf.ScriptMessageContext}

I have also tried other format such as:

var dateCurrentOriginalForecast = new Date('2017-11-09 06:00:00');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00.000Z');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00T');

but I still obtain the same error.

Why? What is the problem? What am I missing? What is a correct date format that is ok for Rhino?

Something similar related to Date objects and Rhino is here but there is not a solution: Javascript invalid date in iOS/Android 2.2

Answer 1

Effectivly it's strange....

Try using explicit date part :

new Date(year, month, day [, hour, minute, second, millisecond ])

new Date('2017','11','09','06','00','00')

Answer 2

It has a different implementation of Date . If Date.parse of the string returns NaN then the string is not interpreted as a valid date and calls of new Date(string) will return a date but InvalidDate .

Split the string dates on its parts and set them separately, or uild string dates that are respecting the Date requirements.
