How to calculate the time difference between date and time?

Hi

 

I have two problems. My data source is a CSV file. It has two columns called BookingStart and BookingEnd

 

 

1) My first problem when I imported my CSV file into Power BI and date and time is mismatching as below

 

For example, the first-row actual booing date is 16.11.2021 but it shows 17.11.2021. Also, the time is 13:08 pm but it shows 2.08 am. Can anyone advise how to fix this?

 

2) My second problem,

 

I need to create a new minutes column between booking end time and booking start time. I can able to add columns and subtract in the Power query. But the average minute's values are not matching properly. It's not recognizing am/pm properly.

Can anyone help with this?

 

Thanks

    bourne2000 for 2nd one, use duration.totalminutes function

     

    Duration.TotalMinutes ( [Start Column] - [End Column] )

    bourne2000 can you change the type from date time to time zone and then in the next step-change it to datetime. let's first check that.

      parry2k  Thanks

       

      When I converted into timezone

       

       

       

      However when I tried to convert back to date/time, the values are changing

       

       

      Please advise

        parry2k It's working thanks. I just extracted time into separate columns

         

         

         

        Can you advise my second question. If I do subtract, then I am getting negative values. I need to create total hour column and total minutes column from the end and start date
