Add hours to existing column

[benjamin_sasin]

Hi, I've got a whole sequence of steps in Power Query and already a bunch of pivot tables connected to the data. I found out that the time input is wrong and believes it's in my current time zone (but it's not). So I have to add + 7 hours. I've done that successfully by adding a column NewColumn = [create_user_date] + #duration(0,7,0,0) , however I would like to replace the current colum instead of adding a new one.

I've learned about Table.TranformColumns, but I can't figure out the actual syntax to do this with my current DateTime.

Any suggestions?

You can add this step.

Replace text in "red font" with your previous step's name

= Table.TransformColumns(#"Changed Type",{"create_user_date", each _ + #duration(0,7,0,0)})

Hi, 

I can't get this to work.. It's asking for a comma after the #duration... 

Any tips?

Okay it's working! Thanks.

What's the underscore for in = Table.TransformColumns(#"Source", {"user_create_date", each _ + #duration(0,7,0,0)})?

_ is the value that is passed as parameter to the function.

In Table.TransformColumns function it is the intersection of current row and Column you have chosen

Another example, If you simply create a new custom column as follows...it will return you the current row as records

= _

This is weird syntax, but why not. Thanks!
