Temporary File Processing and Regex Pattern Matching

The function first creates a temporary file and writes two arguments to it. Then it reads the content of the file and uses a regular expression to find a specific pattern. Next, it converts the matching results to JSON format, gets the current time, and finally writes the result and time to another temporary file, and returns the content of this file. The function integrates file operations, regular expression processing, JSON handling, and time retrieval technologies.
