DatesInPeriod () function accepts it's first parameter as "Date" only with default 12:00:00AM timestamp. What about for different time?

I think it would be useful to me if you not only allowed datesInPeriod to accept timeStamp values but also allowed the interval parameter to support "hour" resolution. Right now, I think the best resolution available is "day". I have a situation where I am computing the the number of times something happened in the last few hours. camargos88 gave me some DAX that worked, but I think it's broke now and it's not entirely intuitive to read. Enhancing the DatesInPeriod function to work with hours might make the DAX more readable and easier to maintain: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Sum-of-Failures-Last-Hour/td-p/1037662 The above forum post is a fictional example of a real problem I am dealing with. It's actually far easier to compute the Sum of Failures (within the last few hours) using a language other than DAX, but DAX is what Power BI offers...
