Hi,
fitting for this day we found a bug concerning the leap year.
See the following example:

Timeliness.parse('2012', :format => 'yyyy', :strict => true)
2012-02-29 00:00:00 +0100

Timeliness.parse('2008', :format => 'yyyy', :strict => true)
2008-02-29 00:00:00 +0100

Timeliness.parse('2009', :format => 'yyyy', :strict => true)
nil

Timeliness.parse('2010', :format => 'yyyy', :strict => true)
nil
Timeliness.parse('2011-02', :format => 'yyyy-mm', :strict => true)
nil

Maybe Timeliness could check for this(29.02.) and return something like 28. 02. instead.

Regards,
Robert
