Add minutes to a time

You can add (or subtract) a number of minutes from a time using fractions.
Dates are represented as sequential whole numbers so 1 hour is equivalent to the fraction (1/24).
Times are represented as fractions based on there being 24 hours in a day.
1 Hour is 1/24 = 0.04166
1 Minute is 1/(24*60) = 1/1440
1 Second is 1/(24*60*60) = 1/86400

Example

	A
1	=TODAY() = Friday 29 November 2024
2	=NOW() = Friday 29 November 2024 11:44:05
3	=A2 + (25*(1/1440)) = Friday, 29 November, 2024 12:09 PM
4	=A2 + TIME(0, 25, 0) = Friday, 29 November, 2024 12:09 PM
5	=A2 + (4/24) + (75/1440) = Friday, 29 November, 2024 04:59 PM
6	=A2 + TIME(4, 75, 0) = Friday, 29 November, 2024 04:59 PM
7	=A2 + (6/24) + (30/1440) , (80/86400) = Friday, 29 November, 2024 06:15 PM
8	=A2 + TIME(6, 30, 80) = Friday, 29 November, 2024 06:15 PM
