I'm not suggesting its anything other than a ridiculous and meaningless thing to write, I was just saying that both GDP and AUM are measured in the same units (USD).
Apparently several people decided this fact was necessary to downvote ¯\_(ツ)_/¯
No GDP is in $/time. Gross domestic product (GDP) is the monetary value of all the finished goods and services produced within a country's borders in a specific time period.
distance/h the per hour is implied when recording distances, however should the race not exactly record 1h the difference is not simply ignored.
Another example, look a records when the physical pools are slightly off of regulation distances for 100m/200m etc. Record keepers in no way ignore those differences.
