You may need to write a Power BI report that works with Unix Epoch Time, converting either to or from it. Epoch Time is simply the number of seconds that have passed since January 1, 1970, at 12:00 am UTC. So at 1 am of that date, Epoch Time would be 3600, since 3,600 seconds have transpired. Today Epoch Time is around 1610644465, or 1,610,644,465 to make it easier to read, though you will never see the commas in a database.
Converting to and from this time format is deceptively simple, as long as you understand a few functions in Power Query and the concept of Duration.
