Converting a date time from utc - daylight saving??

[maurcoll]

Hi

I have a sharepoint file that is generated from a power app. I have startdatetime and enddatetime columns
The issue i am having is that when i load the data from the sharepoint file into power bi desktop the hour reduces by 1 hour. This is in powerquery, I'm not sure if this will be due to daylight saving as i am in the UK or if there is another issue that could be causing this. Any help in how to convert the datetime in the column to return the correct value. I then split the column into a date and a time column.

for example

23/10/2025 13:10 becomes 23/10/2025 12:10

Hi @maurcoll This issue is common with SharePoint and Power BI. SharePoint saves all date and time values in UTC but shows them in your local time zone. When Power BI connects, it retrieves the original UTC values instead of the local ones.

Here is a quick fix:

Go to Power Query -> Transform Tab -> Select the Date Column -> Change Type ->  Date/Time/Timezone

a popup will open select you local time to get it same as sharepoint.

Here is a details guideline

Thanks

@maurcoll You could add a step to add an hour like the following:

AddedHours = Table.AddColumn(Source, "UpdatedDateTime", each [DateTime] + #duration(0, 1, 0, 0), type datetime)
