I am trying to get the handle of build-in variables for: ActualDateAndTime, CurrentTime, ActualTime.

I am using:

handle =  self.api.exchange.get_internal_variable_handle(state, CurrentTime, key_value).

Where i can find those key-values? Thanks.

You seem to be confusing built-in variables with internal variables.

Internal variables are specific to an EnergyPlus object and therefore require a variable_type and a variable_key using self.api.exchange.get_internal_variable_handle(state, variable_type, variable_key).

Built-in variables like ActualDateAndTime are unrelated to EnergyPlus objects. The Data Transfer API provides specific methods for each. For example, you'd use self.api.exchange.actual_date_time(state) to get ActualDateAndTime.

You can read more about built-in variables and internal variables in the EMS Application Guide.

thanks! I appreciate that. It looks like the outputs for ActualDateAndTime, CurrentTime, ActualTime are integers. I am looking for some outputs like: 2/1/2020 3:00:00. Is it doable?

It looks like the outputs for ActualDateAndTime, CurrentTime, ActualTime are all integer values. I am expecting something to be like: 5/1/2020 9:05:00. Is it doable?
