XLS TimeSpan format issue

[Davor]

I'm using: Telerik Reporting Q1 2015 v9.0.15.422

I have some data that is duration information (TimeSpan to be specific). I want to show duration in h:mm:ss  so that we can sum up durations in spreadsheet. However, I'm only able to show duration in hh:mm:ss format which can't be summed up in spreadsheet.  Is there any way to show TimeSpan in h:mm:ss format?

Hello Davor,

We tested exporting a report to Excel and adding the durations together. Please find attached the used sample report and exported XLSX file with the durations sum.
