I'm running a SuiteScript 2.0 script that is using the following javascript code to get the current date/time stamp factoring in time zone. However I have found that when this code runs that it does not always return the same format, on rare occasions it is returning an unexpected/unpredictable date/time formatted values. To test I ran the below code on a schedule and output results to the log, it can take several hours/days but eventually this code eventually returns unexpected values.

JavaScript code I am running:

var now = new Date();

var currentDateZoned = format.format( { value:now, type:format.Type.DATETIMETZ } );
