Duration.Seconds difference between two dates

[ESS]

I am trying to extrapolate the seconds between two dates using the function Duration.Seconds

Duration.Seconds([taglio_data_ora_fine]-[taglio_data_ora_inizio])

in some is correct in others not, how do I solve this problem?

Hi @ESS ,

I think you want to calculate the difference between two dates. You can try DATEDIFF() function in the DAX.

Column =
DATEDIFF ( 'Table'[taglio_data_ora_fine], 'Table'[taglio_data_ora_inizio], SECOND )

Duration.Seconds returns the duration of seconds between two 1-60 second stamps. 

You see your first row thats displaying 54, there is 54 seconds between 57 and 51. 

I think that you can get the correct duration if you subtract the two dates and then convert the value to seconds, (*24*60*60)

You can read more about the Duration functions here, but the short answer is that Duration.Seconds returns the seconds portion of any duration between two dates. 

You'll likely want to use Duration.TotalSeconds([taglio_data_ora_fine]-[taglio_data_ora_inizio]) to get the total number of seconds between the timestamps.

Thank you Resident Rockstar.
This works great in the Power Query transform. 👍

Hi,

I'm not quite sure i understand, is it just the difference between seconds you're after? If so than the image you provided is showing the correct results. 

Or are you after the total duration difference in seconds between two dates? If that is the case you should try and use Duration.TotalSeconds instead.
