Random String Processing and File Output with Time Stamping

This function first generates a random string, then converts it to JSON format, extracts a number from it using regular expressions, calculates the square root of the number, writes the relevant information to a file, and returns the current time. This code covers multiple aspects such as file operations, regular expressions, mathematical calculations, JSON processing, and date and time handling.
