We can also convert from the standard date and time format into Unix epoch time. To see how this works, create a second column in the R03_Table table using the following formula:
UTC2Unix =
VAR __UTC = 'R03_Table'[Unix2UTC]
VAR __SourceBaseDate = DATE(1970, 1, 1)
RETURN (__UTC - __SourceBaseDate) * 60 * 60 * 24
