SharePoint data source: DoBs are interpreted as wr...

Smeegwhet · ‎07-07-2022

Hello,

I have a problem with Importing data from SharePoint site.

The problem is, about half the dates appear (incorrectly) as being 23:00 on the day before, e.g a date of "01/07/2022" on SharePoint will appear as "30/06/2022 23:00"

It looks like only the values from BST are processed this way (approximately from late April to October)

You can see the columns in PowerQuery:
The "Date" field from SharePoint, after having been imported into PowerQueryThe same dates, having been cast to "DateTimeZone"

You can see the values from the SharePoint list, and the column settings here:

The Regional Settings for the SharePoint site are for UTC:

I have absolutely no idea why this is happening.

Other than simply +1 hour to all the values, and then truncate, I don't know:

1. The cause of this problem

2. A neat solution

Any help would be much appreciated!

Hi @Smeegwhet ,

SharePoint Date wrong in Power Bi

SharePoint dates show in Power BI as one day off

However my issue has been resolved by my SharePoint System adminuister. Here is what he has told me?

"All dates are stored as utc and time shifted in the browser to match the regional settings. That's why bst causes a problem because some dates are +1 hr and some aren't. To fix it i took an export of the list to excel and detached it from the list so it didn't update. Then i set the time zone of the sharepoint site to utc, then ran a flow against it looking for dates that had a decimal in them (excel stores dates in weird format of number of days past 01/01/1900), then rounded the date up, formatted it and wrote it back to the sharepoint list."
