ISO 8601 Format problem

Posted on by 171

Hello everyone I have a problem reading a date field from excel in Powerapps. When I try to read it out in PowerApps in my datepicker I get the following error message: The expected value "45328.9583333333" must be a valid RFC 3339 format for "Date-Time". Permitted ISO 8601 formats: 'YYYY-MM-DDThh:mm:ssZ', 'YYYY-MM-DDThh:mm:ss thh:mm', 'YYYY-MM-DDThh:mm:ss'.

 

The interesting thing is that i can patch the date from the datepicker into the excel but when i read it out i get the error message and the datepicker is empty.

 

Thats how i patch it: 

 

{'dateColumn': datepicker.SelectedDate +1};

 

 

and thats how i view it in the datepicker

 

gallery.Selected.dateColumn

    hey @alt88 

     

    can you try this please:

    DateAdd(
     DateValue("1899-12-31"),
     RoundDown(gallery.Selected.dateColumn, 0),
     Days
    ) + Time(
     Hour(Mod(gallery.Selected.dateColumn, 1) * 24),
     Minute(Mod(gallery.Selected.dateColumn, 1) * 1440),
     Second(Mod(gallery.Selected.dateColumn, 1) * 86400)
    )
