Based on provided context information above I can provide you with an overall approach for this problem which includes steps of planning, executing tasks in a systematic way using Python's logging module as well documentation strings (Dunder methods) if needed so that we know what each method does under certain conditions and how they behave. Please note it might be helpful to review your code again after you have successfully implemented the task due diligence for bugs or issues before proceeding with this plan:
 1- Import necessary modules at top of file using Python's logging module - `import sys, traceback`;  2nd step is reading all context files mentioned in provided list and storing them into a dictionary. The keys will be filenames while values are contents from each respective document (using python’s open function to read the content) . Then initialize logger at top of file using Python's logging module with appropriate handlers for sending logs over email or other medium according requirements; 3rd step is creating a method named "convert_time" which will perform actual time conversion operation based on provided inputs. Use traceback in this function to log any errors and exceptions that occur during execution of the code - finally, return final converted datetime object after successful completion else logs with exception details if something went wrong; 4th step is testing method 'read' using files from your context dictionary as input arguments (use sys module for getting filename) while logging each file content before calling function. This way you can track every line of code execution and find out bugs in different sections simultaneously due to multiple developers working on same project at the time; 5th step is writing detailed documentation string inside functions which describe what they do, input parameters thematic information (use python's dunder methods), output data type/value that it returns etc. This will be helpful when someone needs help in understanding or implementing a specific part of your code - also this would ensure maintainability and readabilty by team members working on the same project; 6th step is writing end-of-day tasks report detailing all changes done, failed tests due to bugs/issues detected during execution etc., it will be helpful in keeping track for future reference.
