date format issue

[jbreher]

Running timesetter with the last item in the date column set to "12/15/14", I get :
hostname:timeline user$ timeline-setter -c /Users/user/Desktop/timeline/t.csv
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/time.rb:264:in `local': argument out of range (ArgumentError)
...
Changing that date to "12/11/14" works. As does "12/12/14". "12/13/14" breaks again. One might expect it is parsing the "13" as the month.

Changing this to "December 15, 2014" works.

The workaround seems clear - I just figured someone might like to know.
