Adding decimal hours to start time

[Learner_Kat]

Hi All,

I have a column start time 09:00 am(hard coded),and another column with hours of the day I need to create a new  end time which must add hours per  day to 9 :00 am

I tried this DateTimeAdd("2016-03-30 09:00:00",tonumber([Hours per Day]),"hours" ) .  

If [hours per day]  is decimal hours e.g 4.5 then it does not work correctly.

Start time   hours per day       end time

9:00            4.5                        13:30

9:00            4.0                        13:00

9:00             2.0                        11:00

Any help please.Thanks

@Learner_Kat One way of doing this

Hi, @Learner_Kat 

Any fraction in the duration is truncated. For example, you cannot add "1.5 hours". Instead, add "90 minutes".

So, maybe you can use the formula:

DateTimeAdd("2016-03-30 09:00:00",tonumber([Hours]) * 60 ,"minutes" )

or 1 step by formula:

Spoiler

DateTimeFormat(DateTimeAdd("2016-03-30 09:00:00",tonumber([Hours]) * 60 ,"minutes" ),"%H:%M")
