Hello,
"I want to create a parameter that sets default values for prompts (i.e., the default values should be epoch seconds), and this default value should replace the value in the RunIdentifier field, which is created in the Formula tool. This way, when the workflow is run, the default value (epoch seconds) will be generated and stored in the RunIdentifier field."
@rashmiks By default the Date tool shows the current date, you can use that for your application
@binuacs
I want the current time to be dynamically populated as the default value in the Text Box when the user runs the app, without it being hardcoded in the Formula Tool.
@rashmiks you can create something like the attached workflow, which takes the date from the user and adds the current time dynamically with the date
