Hi,
yep, this is unfortunatly an issue indeed.
First option: use the ecosystem action "GetTimeSpanInfo", feed it seconds, and you get the total minutes as a float which you can then round to in, which gives you 61

Second option, I make a copy of the playmaker action on the ecosystem and add new entries that will give you the roundeddown version of these values.
Let me know if the second option suits you better, and I upload that action.
Bye,
Jean
