Generate Go commit message

Create a conventional commit message for Golang changes.

You can query a model directly and test the results returned when using different parameter values with the Cloud console, or by calling the Vertex AI API directly.

I'm adding new features to a Go application that saves the current system timestamp into a file. Write a commit summary that describes the changes above.

Response

Of course. Here is a commit summary that follows the conventional commit standard:

feat(output): add support for JSON output

In addition to the plain text file, the application now saves the current timestamp to a `current_time.json` file.

This provides a structured data format, making the output easier for other programs to parse and consume. A new `saveToJSONFile` function and a `TimeData` struct have been added to handle the JSON marshaling and file writing.
