|
|[ensemble] ~/p/ruby/src/ruby $ ./ruby -e "p Time.local(2004, 'feb', 32, 1, 1, 1)"
|-e:1:in `local': argument out of range (ArgumentError) from -e:1
|
|It doesn't do it if the day-of-month is past 31?
|
|So, I think it is a bug, not a feature.

This is caused by rather stupid (but simple) date range check.  I'm
not sure what is the best way.  No check?  Or strict check?
Discussion welcome.
