Below is an example of how to implement the Epoch Date Time Conversions Functionality.

1. Download and install the Epoch Date Time Conversions 

Open the Forge Epoch Date Time Conversions webpage and download the component. The demo application can also be downloaded. Install it.

2. Create the Epoch Date Time Conversions dependency

Open the Manage Dependencies option and search for Extended DateTime. Select from the Epoch Date Time Conversions the action or actions for your purposes and apply changes. 

3.  Create Local Variable(s) in a screen or block

To have better control and to manage the sources of your data, it is suggested to create local variables, by choosing Date and Time Data Types, which then will be used as input parameters for the selected function.  Observe that some functions do NOT require any input parameters while others require  both input and output parameters

4. Assign Values to Parameters

You can use other sources of data, the standard Input widget or you may prefer to use selection widgets such as the Date Picker and or the Time Picker to assign values to the Date or Time Parameters

5. Create the Action Flow for the purpose of refreshing the calculations

Create a Flow to integrate the Action that refreshes the calculations, when new data is inserted or selected, in order to get the return of the function. The Action should be connected to a Screen or Block using a button or a link to perform it.
