new_interval output with Date object inputs #219

I obtain unexpected results when giving Date objects to new_interval. Shouldn't the below code give the same output in both cases?

new_interval(ymd('2011-01-01'), ymd('2013-01-01'))
## 2011-01-01 UTC--2013-01-01 UTC

new_interval(as.Date('2011-01-01'), as.Date('2013-01-01'))
## 2010-12-31 18:00:00 CST--2012-12-31 18:00:00 CST

It's the same interval but in different timezones. It's not necessarily wrong, but it goes agains the value of tz(as.Date('2011-01-01')) . So I have changed interval to default to UTC as other lubridate functions do.
