I am finding 5 min interval records for date range records (in datetime format) for which I am using List.DateTime function so far in Power query. This function works well in Custom column as shown below:
Actually my model exist on Azure analysis services and some how when I use List.DateTimeZones function there it doesnt recoganise it. I am planning to use List.DateTime only after finding the DateTime Value from timezone fields.
As Azure analysis services was not recoganizing List.DateTimeZones function so I calculated Datetime value from datetimezone field and then used List.DateTime function. It worked! For Power BI List.DateTimeZones function is working fine.
