Add and Subtract Two Times :
01 : 10 : 00
06 : 50 : 00


Sum :
Step 1 : Add seconds first
00 + 00 = 00
Step 2 : Add minutes
10 + 50 = 60
Step 3 : Add hours
01 + 06 = 07
time --> 07 : 60 : 00
We know that 60 minutes is equal to 1 hours. Hence add 1 hour to 07 hours. Thus the sum of two times is 08 : 00 : 00

Difference :
06 : 50 : 00
01 : 10 : 00
