Make adjustments to the timestamp of .jpg and .mp4 files names

TimeStamp_Adjust.py

# Make adjustments to the timestamp of .jpg and .mp4 files names
#
# This is useful if your camera's clock is wrong or not handling daylight saving time.
#
# Place this Python file in a folder that has .jpg and .mp4 files from the Maxto M3 camera.
# When you run the script, it will rename files by subtracting changeHour and changeMinute 
# from the formatted time in the filename.  It will do the same for the file Modified date.
# You will be prompted to enter a password.  If no password is entered it will run a test
# and put the results into the log file.
# 
# Example output:
# 20231108200516_009309.MP4, 20231108190216_009309.MP4, 2023-11-08 20:08:16, 2023-11-08 19:02:16
