Sorry cedric, but after updating to 2.2.0 the ordering of users is still not as I think you intended. when I order users on last logged in, it shows me:
10 minutes, 13 days, 13 days, 17 hours, 18 days. 2 hours
when i sort on modified (descending) it shows me:
a year ago, a month ago, 6 month ago
Hello @pimzwager,
Looks like you are using the old version of the js.
Could you clean your browser cache, and tell us if the issue is still occurring ?
Cheers,
Cédric
ok, now i feel really stupid 
cleared my cache and now it works.
thank you for your fast reply.
No problem @pimzwager
We added a mechanism to avoid the js to be cached by the browser, maybe the html was cached.
