Remove seconds from time in Power Query Editor
I have a time column in an existing table. I want to remove the seconds so that it will relate to a Time table column that is in hh:mm format (no am/pm). I know this is likely easy, but I cannot figure out the m code in order to do this. Help will be greatly appreciated.
I punted on trying to change the format of the time column.
I changed my time dimension table to use seconds as the smallest grain. Doing that and then relating it to the time column in my source table did the trick.
This is where I found code for a time dimension table:
https://ginameronek.com/2014/10/01/its-just-a-matter-of-time-power-bi-date-time-dimension-toolkit/
I changed
Source = List.Times(#time(0, 0, 0),MinuteCount, #duration(0,0,1,0)),
to
Source = List.Times(#time(0, 0, 0),86400, #duration(0,0,0,1)),
to get a seconds grain.
Works fine, no noticible lag in performance.

Perhaps:
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjSwMjawMjFVitUBcgytTEysjI2VYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type time}}), #"Duplicated Column" = Table.AddColumn(#"Changed Type", "Column1 - Copy", each Text.From([Column1], "en-US"), type text), #"Changed Type1" = Table.TransformColumnTypes(#"Duplicated Column",{{"Column1 - Copy", type time}}) in #"Changed Type1"I have tried something similar before. The issue is that the data coming from Salesforce is in this format:
7/26/2018 8:20:17 PM I can successfully split that column into date and time, with the time in the format h:mm:ss AM/PM
The time table I have is in the format hh:mm. So 13:45 is a value.
The code for the time table starts like this:
GENERATESERIES ( 1, 1440, 1 )
, "TimeValue", TIME ( 0, [Value], 0 )I don't want to create the time table at the seconds grain because I don't need that accuracy, and I don't want that big a table. So I'm trying to transform 8:20:17 PM into 20:17, but still a time type.
How about this?
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjSwMjawMjFVitUBcgytTEysjI2VYmMB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type time}}), #"Duplicated Column" = Table.AddColumn(#"Changed Type", "Column1 - Copy", each Text.From([Column1], "en-US"), type text), #"Removed Columns" = Table.RemoveColumns(#"Duplicated Column",{"Column1 - Copy"}), #"Duplicated Column1" = Table.DuplicateColumn(#"Removed Columns", "Column1", "Column1 - Copy"), #"Split Column by Delimiter" = Table.SplitColumn(Table.TransformColumnTypes(#"Duplicated Column1", {{"Column1 - Copy", type text}}, "en-US"), "Column1 - Copy", Splitter.SplitTextByDelimiter(":", QuoteStyle.Csv), {"Column1 - Copy.1", "Column1 - Copy.2"}), #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1 - Copy.1", Int64.Type}, {"Column1 - Copy.2", type text}}), #"Split Column by Delimiter1" = Table.SplitColumn(#"Changed Type1", "Column1 - Copy.2", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Column1 - Copy.2.1", "Column1 - Copy.2.2"}), #"Changed Type2" = Table.TransformColumnTypes(#"Split Column by Delimiter1",{{"Column1 - Copy.2.1", Int64.Type}, {"Column1 - Copy.2.2", type text}}), #"Removed Columns1" = Table.RemoveColumns(#"Changed Type2",{"Column1 - Copy.2.2"}), #"Changed Type3" = Table.TransformColumnTypes(#"Removed Columns1",{{"Column1 - Copy.1", type text}, {"Column1 - Copy.2.1", type text}}), #"Added Custom" = Table.AddColumn(#"Changed Type3", "Custom", each [#"Column1 - Copy.1"] & ":" & [#"Column1 - Copy.2.1"]) in #"Added Custom"
