So I have 2 times, say 07:30 and 09:30. I was trying to subtract time in PBI, and that will get me decimal hours, multiplying it by 24 will get me 1.5 instead of 1:30 (1 hour and 30 minutes).
So I went to original access database and there I subtracted time using this: format(time2-time1,"short time").
Importing this column into PBI, it shows 1:30 but it is as a text column. Converting it to time column makes all column into error. I need it to be time since I will be adding the numbers up, and text you cannot add up.
Would like to know if there is either some way to find time difference within PBI in hours and minutes OR not converting access column into text when importing.
By my tests in power bi, it seems that Date2-Date1 is like below.
If it is convenient, could you share the dummy pbix file which can reproduce the scenario, so that we can help further investigate on it? You can upload it to OneDrive and post the link here. Do mask sensitive data before uploading.)

The error already exists in your post. When you subtract time, it is giving time in AM and PM.
For example, if I subtract 7 AM from 10 AM, i require 2 hours, not 2 AM. The reason being is that I need to subtract 2 hours from another hours time. It will not be possible to subtract 2 AM from say 10 hours (which itself would be 10 AM).
The solution is that i subtract time and get decimal hours and then times it by 24 hours. However, for some numbers I will get exact hour, but if the time difference is 1 hours and 30 minutes, it will output the time as 1.50 instead of 1:30.
You actually don't need to go to Access to do the date/time calculation. In Power Query is much simpler. Once you've imported the respective columns you may change the data type as Date / Time. Now follow the steps given below and match it with the screenshot attached.
Step 1: Select the columns
Step 2: Add Column tab --> Time --> Subtract. It will create a new column that will have the difference between both the columns
Step 3: Select the SUBTRACT column
Step 4: Select the Duration --> Select Total Minutes (or anything else as per your need)
Step 5: Total Minutes column has your solution
Hope this works.
If this is the solution then please do mark it as a solution.
