lubridate::floor_date(lubridate::ymd("2016-03-31", tz="Europe/Helsinki") , unit="month")
returns [1] "2016-02-29 23:00:00 EET"
I expected this to return "2016-03-01 EET".

As a comparison
lubridate::floor_date(lubridate::ymd("2016-03-01", tz="Europe/Helsinki") , unit="month")
returns [1] "2016-03-01 EET"

and so do all dates between "2016-03-01" and "2016-03-27". The error seems to occur for

"2016-03-28"
"2016-03-29"
"2016-03-30"
"2016-03-31"
