Numbers: Cell time calculation not adding the correct time

Question

Greetings,
First, thank you in advance for your assistance. I have searched the board and where there are many great formulas, I have not found the answer to this challenge.
Cell A1 has a time for example 5:45 PM
Cell C1 has an amount of minutes for example 40
Cell B1 should be adding 40 minutes to 5:45 PM for result of 6:25 PM
Cell A2 picks up the value of Cell B1 as its starting value so that it can calculate the same formula for the next line.
This document is a schedule so that it adjusts the times based on the amount of minutes a segment is. I can post an excel file if that will assist, the excel formula for this in the B cell is A1+TIME(0,C1,0)
Again thank you in advance for any assistance in solving this challenge.

Answer 1

=TIME(HOUR(A),MINUTE(A)+C,0)
• Every time I may use them, I uses the "short references", those with no row num embedded.
• The TIME function requires three parameters,
a number of hours,
a number of minutes
a number of seconds
but the formula parser is fair enough to understand that, when the given number of minutes is greater than 59, it means some hours + some minutes.
And of course, mutatis mutandis, it's the same for the number of seconds.
This is why, when I want to display with the current format hh:mm:ss a decimal time value as those resulting of calculations, I don't spent time to isolate the number of hours, the number of minutes, the number of seconds. I just calculate the total number of seconds.
if cell B2 contains 0.1234490740741
I type =TIME(0,0,B24*6060) in cell C2
Then, applying the yy:mm:ss format I get 02:57:46
inserting =TIMEVALUE(C) in D2, I get 0.1234490740741
I know that this behavior is not described in the Help.
I don't feel that it's a sin.
It's for passing this kind of details that the forum exists.
I feel perfectly odd questions whose response is available in the Help but it's always a pleasure to help users to discover features which are only available "between the lines".
