DateComponentFormatter behaviour inconsistency

I noticed the output when running the following on different mac dev machines. Anyone know more detail on this?

let formatter = DateComponentsFormatter()
formatter.allowedUnits = [.hour, .minute, .second]
formatter.unitsStyle = .brief

the output changed from 233hr 55min 35secs to 233hrs 55min 35secs

on another machine, the output is 233hrs 55min. 35secs.

Thanks in advance!

Which are the languages used for this testes?
