Converts a time string to a time string in milliseconds.

Converts a time string to a time string in milliseconds.

Two days ago, I met a time to convert the string format to the time expressed in milliseconds. As a beginner, I suddenly had no clue, so I could only search for various types. Finally, the desired results are achieved. Run the code first. If something is wrong, I hope you can correct it.
