Process Purpose

The Date/Time Operations process is used to calculate a date, when days are added to a given starting date. The result is stored in a variable.

Check the provided Date/Time Operations examples at the end of the topic.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Date/Time Operations process. In this case, the properties window includes 2 tabs - "General" and "Error".

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

"General" tab

Proceed as follows:

Starting Date
Date	Define the value for the “Starting Date”. Either enter it OR click and select a variable with that value. See Variable Definition.
Format	Select a “Starting Date” format from the drop-down. You can write a date format with the use of a syntax list that is accessed by clicking . See Accepted Syntax List. This format needs to match the format of the date/time value from "Date". Ex: For a "Date" presented like this: 22/07/2018, use the following format: %D%/%M%/%Y.
Operation
Operation	Check the required operation: •"Add" - this operation adds the defined value to the "Starting Date". •"Subtract" - this operation subtracts the defined value to the "Starting Date".
Value to Add	Enter the number of time units to be added/subtracted OR click and select a variable with that value.
Interval	Define the type of time units to be added by selecting one from the drop-down (“Days”; “Quarters”; Months”; “Weeks”; etc.).
Result
Result Variable	Click to define the variable that will receive the result value. See To Select/Create a Variable.
Output Format	Select the intended output format from the drop-down OR enter your own format which must comply with the available syntax list that is accessed by clicking . See Accepted Syntax List.

Proceed to the "Error" tab.

"Error" tab

Detail of a window:

"S:Menu" is a screen included in the same program as the process.

"R:Routine_1" is a routine included in the same program as the process.

If required, use the icon, on the upper right corner of the properties window, to attach any relevant notes to this process.

Date/Time Operation Examples

- Start Date format = Date (YYYYDDMM) >> Output format = Date (DD/MM/YYYY)

- Start Date format = Date and Time (YYYYMMDDHHMMSS.MS) >> Output format = Date and Time (DD/MM/YYYY HH:MM:SS.MS)

- Start Date format = Date and Time (YYYY-MM-DDHHMMSS.MS) >> Output format = Date and Time (DD-MM-YYYY HH:MM:SS.MS)
