Minute
The ‘Minute’ dimension reports the minute that a given metric occurred (rounded down). The first dimension item is the first minute in the date range, and the last dimension item is the last minute in the date range. This dimension is valuable for trended reports, as it allows you to see metrics over time. Given how granular this dimension is, Adobe recommends limiting the reporting date range to one or two days.
Populate this dimension with data
This dimension is derived from the timestamp of each hit. There is no variable to set; it works out of the box in any implementation.
Dimension items
Dimension items include a given minute within a report’s date range alongside its date. It is formatted as HH:MM YYYY-MM-DD. Dimension items starting with 00:00 equate to midnight on that day, while values starting with 23:59 equate to 11:59 PM for that day.
