    IN1 : DATE;
    IN2 : TIME_OF_DAY;
  END_VAR

The return type is DATE_AND_TIME. IN1 is DATE and IN2 is TIME_OF_DAY.

Inputs

Name	Type	Description
IN1	DATE	The date component.
IN2	TIME_OF_DAY	The time-of-day component.

Outputs

Name	Type	Description
Return value	DATE_AND_TIME	The combined date and time-of-day.

Description

Combines the date portion from IN1 with the time-of-day portion from IN2 to produce a DATE_AND_TIME value. The time-of-day value is converted from milliseconds to seconds before being added to the date.

Note

Sub-second precision from the TIME_OF_DAY input is lost because DATE_AND_TIME is stored in whole seconds.
