Environment

jRuby 9.2.0.0+ (may also happen on prior versions)
Tested on OS X and Linux.

Expected Behavior

irb(main):001:0> Time.now
=> 2018-11-05 23:32:54 -0600
irb(main):002:0> Date.today
=> #<Date: 2018-11-05 ((2458428j,0s,0n),+0s,2299161j)>

Actual Behavior

irb(main):001:0> Time.now
=> 2018-11-05 23:32:54 -0600
irb(main):002:0> Date.today
=> #<Date: 2018-11-06 ((2458428j,0s,0n),+0s,2299161j)>

What appears to be happening here is that since the DST shift occurred on 11/04 at 2am, after 11pm each day thereafter (presumably until DST begins again in March), Date.today returns the next day. This does not happen if doing Time.now.to_date.
