Absolute Date Time is a utility component that prevents OutSystems from automatically converting DateTime values between local time (timezone) and UTC when exchanging data between the client and server.

By default, OutSystems converts DateTime attributes to UTC when they are sent to the server, or to the Device's timezone when receiving from the server. This behavior can cause unintended time shifts, particularly with user-inputted values like appointments, deadlines, or fixed timestamps.

Absolute Date Time offers a simple, non-intrusive solution: developers can disable these automatic conversions by naming attributes in a specific way.
