It seems to me that the test time limit in gateway quizzes is converted to seconds from minutes when exported. 60 minutes correctly becomes 3600 seconds.
I would suggest to have the same units everywhere in order to avoid confusion and mistakes.
Seems to be a good suggestion. Issue opened on GitHub so one of "us" will hopefully fix for a future version of WW.
