Formula
Time Addition Calculation Formulas:

1. Convert all time values to seconds:
   - HH:MM:SS format: Hours×3600 + Minutes×60 + Seconds
   - HH:MM format: Hours×3600 + Minutes×60
   - MM:SS format: Minutes×60 + Seconds
   - Hours (decimal): Hours×3600
   - Minutes (decimal): Minutes×60

2. Calculate total seconds:
   Total seconds = Sum of seconds for all time values

3. Convert total seconds to desired format:
   - HH:MM:SS: Hours = Total seconds÷3600, Minutes = (Total seconds%3600)÷60, Seconds = Total seconds%60
   - Total hours: Total seconds÷3600
   - Total minutes: Total seconds÷60
   - Total seconds: Total seconds
   - Days:Hours:Minutes: Days = Total seconds÷(24×3600), Hours = (Total seconds%(24×3600))÷3600, Minutes = (Total seconds%3600)÷60
