Solved: Re: Time Zones and Scheduled Refresh

mterry · ‎03-20-2019

I created a table to show the latest refresh day and time for my reports, had issues when I scheduled a refresh through the Power BI service, and reading through here found the cause of the error (I believe). In the code below the LocalNow() portion is using UTC time when the refresh gets scheduled through the service whereas it's using my time on my local machine through the desktop app.

= #table(type table[LastRefresh=datetime], {{DateTime.LocalNow()}})

So I updated my table to pull the UTC date & time, then added a column that adjusted the time zone. However, I'm still having issues, and I don't understand why, code is pasted below. If I'm using the Utc time as an anchor, why is my 'LastRefreshLocal' column still pulling UTC time instead of switching to my local time zone?

let
Source = #table(type table[LastRefresh=datetimezone], {{DateTimeZone.UtcNow()}}),
#"Added Custom" = Table.AddColumn(Source, "LastRefreshLocal", each DateTimeZone.SwitchZone([LastRefresh],-6,0)),
#"Renamed Columns" = Table.RenameColumns(#"Added Custom",{{"LastRefresh", "LastRefreshUTC"}}),
#"Changed Type" = Table.TransformColumnTypes(#"Renamed Columns",{{"LastRefreshLocal", type datetimezone}})
in
#"Changed Type"

Yes, I have the value displaying on my reports so the user knows when the data was last refreshed

Here are the M steps that I used that seem to work fine (CentralTimeOffset is a parameter)

Though they don't look much different to what you are doing

Good Luck

#"Added Refresh Date Time (UTC)" = Table.AddColumn(#"Changed Type", "Refresh Date Time (UTC)", each DateTimeZone.UtcNow(), type datetimezone),
#"Added Refresh Date Time (CST)" = Table.AddColumn(#"Added Refresh Date Time (UTC)", "Refresh Date Time (CST)", each DateTimeZone.RemoveZone ( DateTimeZone.SwitchZone ( [#"Refresh Date Time (UTC)"], -CentralTimeOffset ) ), type datetime)
