In the reference documentation it says the “date interval type” stores a number of milliseconds and that you can do math on it. https://bubble.is/reference#Data.Messages.date_range.range_greater_than
Specifically: “Adding and subtracting Date intervals always performs absolute math, not calendar-aware math”
I thought that would be a good way to track how long people are spending doing different things in my app.
But when I try to add two date intervals together the only option is to convert the date interval into days/hours/minutes/seconds and then I can do math on those, but I can’t convert days/hours/minutes/seconds back into a date interval.
So how do I add and subtract date intervals?
