Here are a couple of quick calculations to convert Unix time to UTC time and vice versa.
Unix2UTC = VAR UnixDays = MAX([UnixTime])/(60*60*24) RETURN (DATEVALUE("1/1/1970")+UnixDays)
UTC2Unix = VAR __utc = [Unix2UTC] RETURN (__utc - DATEVALUE("1/1/1970"))*60*60*24
Thank you @Greg_Deckler . The first calculation worked for me, although I had to remove the MAX formula, and first had to extract the numbers from the /Date(, but otherwise perfect!
