last failing on first of the month

This works:

Chronic.parse("last 11:00", :now => Time.parse("2015-04-02 14:01:19 UTC"))
=> 2015-04-01 11:00:00 +0000

This doesn't:

Chronic.parse("last 11:00", :now => Time.parse("2015-04-01 14:01:19 UTC"))
ArgumentError: argument out of range

The difference between the two is the date.
