Current time + current times around the world

I need to display the current time at 4 different locations as in the image below:



I can get this to work using a 'Now()' function for Brisane and then using the method of  'Now() - 1/24', however when I publish the report it changes the time. Does anyone know what time power BI works in, I thought it might be GMT but that doesnt line up.

Thanks in advance.
