Letting excel calculate the time..

Recently while doing some event planning, I realised how bad I am at adding time. What's 1 hour 35 minutes after 17:40? Brain functional freeze...

I set my mind to rest my brain and let excel do the calculating and crossed over to the world wide web. Unfortunately Google doesn't auto calculate via the search bar. Best bet for now - Excel does a pretty good job at it, since my brain doesn't.

Formula =CELL +TIME(HOURS, MINUTES, SECONDS)

e.g. =A1+ TIME(1, 35,0)

A1 being the cell that contains the time value, in this case 17:40. And the answer is 19.15.
