This class provides methods for performing operations on SimpleDateTime objects, such as instantiating objects, for exampleThe class is used to conduct operations on SimpleDateTime objects, for example, instantiating objects.

You can also use this class to perform calculate, change formats of the date-time operations, such as calculations, formatting or converting between date-time or convert between the formats.

SimpleDateTime(dateTime)

Instantiates Use this constructor to instantiate a new SimpleDateTime object with the current or transferred date/time. Specify the date and time value in the UTC timezone.
