Time Delta with negative hour handling

DonPepe — Fri, 29 Oct 2021 17:29:08 GMT

Good Afternoon,

I am currently looking for a solution to get the duration between two Date-Time value.

The issue is that I have to handle positivie and negative hour like in these 3 different scenarios :

End time > Start time
End time < Start time
End date <> Start date

Here an exemple of the 3 scenarios.

Activity Type Start time End time

Drive	20-10-21 00:06	20-10-21 00:11
Time correction	20-10-21 01:10	20-10-21 00:06
Drive	20-10-21 23:06	21-10-21 00:22

Do you know how I can have the duration in hh:mm:ss of each activity ?

Thank's in advance,

Don

DonPepe Just subtract them then turn that into seconds and then you can use Chelsie Eiden's duration.

Column = ([Start] - [End]) * 1. * 24 * 60 * 60

Simple enough to handle it in PQ,

let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WcinKLEtV0lEyMtA1NNA1MlQwMLAyMEMTMDRUitWJVgrJzE1VSM4vKkpNLsnMzzu0AEWZoZWhAaZBIH1gO1BVGxlDbTFCqDYyUoqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Activity Type" = _t, #"Start time" = _t, #"End time" = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"Activity Type", type text}, {"Start time", type datetime}, {"End time", type datetime}}, "fr"), Dur = Table.AddColumn(#"Changed Type", "Duration", each let dur = List.Max({[End time]-[Start time], [Start time]-[End time]}) in Text.Format("#{0}h : #{1}m : #{2}s", {Number.RoundDown(Duration.TotalHours(dur)), Duration.Minutes(dur), Duration.Seconds(dur)})) in Dur
