### Answer Based on the available sources, the Extract Dynamic Variable Node is designed to extract information from conversation and store it as a dynamic variable. [(1) ]() The supported variable types are: - Text - Any word or sentence - Number - A numeric value - Enum - A value from a predefined list - Boolean - True or false The documentation does not explicitly mention using existing dynamic variables (like

{{current_time}}

) as inputs or for setting values within Extract Dynamic Variable nodes. The node appears to be intended for extracting values from what the user says during the conversation, not for transforming or combining existing dynamic variables. If you need to work with

current_time

to derive a new variable value, you may need to handle this logic through a custom function that receives the current time and returns the processed value, rather than through the Extract Dynamic Variable node itself. Check out these potentially useful sources: - [Extract Dynamic Variable Node]() - [Extract Dynamic Variables]() Would you like me to provide a general answer on how you might approach this with a custom function?
