Use this This class provides methods to conduct operations on SimpleDateTime objects, for example, instantiating : instantiate objects, and to calculate, change formats of the date and time formats, or convert between the formatsthem.

SimpleDateTime(dateTime)

Use this constructor to instantiate a new SimpleDateTime object with the current or transferred date and time. Since the object keeps date and time in the UTC timezone, ensure the data you pass to the object is in UTC, otherwise your results will be invalid.

Parameter(s):

Name	Type	Mandatory	Default Valuevalue
dateTime	String	N	''

Example:

Code Block

language	js
theme	Eclipse
title	SimpleDateTime()
linenumbers	true

const nowDateTime = new SimpleDateTime();
//
const registrationDateTime = new SimpleDateTime(record.registration_datetime);
//
const yearStartDateTime = new SimpleDateTime('2019-01-01 00:00:00');

You can also use the values in relative format for the SimpleDateTime constructor. All formats are available in the Relative Formats article.
