My data has a DateTime field with values such as:
10/12/2011 2:56:07 PM
10/12/2011 2:58:58 PM
I need to group my data by 30-minute intervals in Power Query. I'm not sure how to do this. I can use:
Time.Minute( [StartDate] )
This returns the minutes. But what I need is to say something like "If minutes > 29 then 30 else 00", and combine it with the date and hour value so I get a datetime back that tells me what 30-minute period the time value fell into (both of
the above would fall in the 2:30 block).
I do this a lot in Excel with formulas, but can't figure out how to do it in Power Query.
