DateDiff formula not working

(0) ShareShare
ReportReport
Posted on by kanwals360

Hi All,

 

I am building an app and trying to calculate Total Hours out from (Time: Left Depot, Time: Arrival on Site, Time: Off Site, Time: Arrive at Depot)

 

Below is my formula and obviously something is wrong with the formula as it is not calculating the Total hour correctly.

 

Any help would be greatly apricated.

Abs(
    DateDiff(
        DateTimeValue(Text(DateValue1.SelectedDate, "[$-en-US]yyyy-mm-dd") & " " & Text(HourValue1.Selected.Value, "00") & ":" & Text(MinuteValue1.Selected.Value, "00")),
        DateTimeValue(Text(DateValue2.SelectedDate, "[$-en-US]yyyy-mm-dd") & " " & Text(HourValue2.Selected.Value, "00") & ":" & Text(MinuteValue2.Selected.Value, "00")),TimeUnit.Hours

    Hello,

    It's difficult to answer this question without proper testing, but here's my attempt 🙂

    Abs(
 DateDiff(
 DateTimeValue(DateValue1.SelectedDate & " " & Text(HourValue1.Selected.Value, "00") & ":" & Text(MinuteValue1.Selected.Value, "00")),
 DateTimeValue(DateValue2.SelectedDate & " " & Text(HourValue2.Selected.Value, "00") & ":" & Text(MinuteValue2.Selected.Value, "00")),
 Hours
 )
) +
Abs(
 DateDiff(
 DateTimeValue(DateValue2.SelectedDate & " " & Text(HourValue2.Selected.Value, "00") & ":" & Text(MinuteValue2.Selected.Value, "00")),
 DateTimeValue(DateValue3.SelectedDate & " " & Text(HourValue3.Selected.Value, "00") & ":" & Text(MinuteValue3.Selected.Value, "00")),
 Hours
 )
) +
Abs(
 DateDiff(
 DateTimeValue(DateValue3.SelectedDate & " " & Text(HourValue3.Selected.Value, "00") & ":" & Text(MinuteValue3.Selected.Value, "00")),
 DateTimeValue(DateValue4.SelectedDate & " " & Text(HourValue4.Selected.Value, "00") & ":" & Text(MinuteValue4.Selected.Value, "00")),
 Hours
 )
) +
Abs(
 DateDiff(
 DateTimeValue(DateValue4.SelectedDate & " " & Text(HourValue4.Selected.Value, "00") & ":" & Text(MinuteValue4.Selected.Value, "00")),
 DateTimeValue(DateValue1.SelectedDate & " " & Text(HourValue1.Selected.Value, "00") & ":" & Text(MinuteValue1.Selected.Value, "00")),
 Hours
 )
)

     

    I removed unnecessary text formatting for the date portion (Text(DateValue.SelectedDate, "[$-en-US]yyyy-mm-dd")). If you use SelectedDate, it's already in a format that DateTimeValue can recognize.

    Try to ensure that the date and time values are selected correctly by users (DateValue.SelectedDate, HourValue.Selected.Value, and MinuteValue.Selected.Value), as any incorrect input might lead to unexpected results. Also, make sure the order of the dates and times aligns with your intended calculation.

    Hi,

     

    I think the error here is that you are adding time between your 4th value and your first which is effectively doubling the total time.

    Also you are calculating the times between each values. If you know that the times will start with Time: Left Depot and end with Time: Arrive at Depot, you could calculate only the time between these 2 values.

     

    Best regards
