Review comment:
       Thank you, @guiyanakuang . 
   
   Previously, `.replace("07:00", "0700")` seems to do the following?
   ```
   - 2021-10-19T07:00:01.683210-0700
   + 2021-10-19T0700:01.683210-0700
   ```
   
   Then, could you give some example for the following?
   ```
   datetime4Str = datetime4Str.substring(0, datetime4Str.length() - 5) + "0700";
   ```
