Maybe add a "safe => 1" (with new, add, subtract) such that the
following
don't die() anymore:

perl -MData::Dumper -MDateTime -e'
     $dt = DateTime->new( safe =>1,
         year => 2008, month => 3, day => 25, time_zone =>
"Africa/Cairo",
     )->add(months => 1);
     print Dumper($dt)
' |less

perl -MData::Dumper -MDateTime -e'
     $dt = DateTime->new( safe => 1,
         year => 2008, month => 4, day => 26, time_zone =>
"Africa/Cairo",
     )->subtract(days => 1);
     print Dumper($dt)
' |less

perl -MData::Dumper -MDateTime -e'
     $dt = DateTime->new( safe => 1,
         year => 2008, month => 4, day => 25, time_zone =>
"Africa/Cairo",
     );
     print Dumper($dt)
' |less

They should all return "2008-04-25 01:00:00" I suppose.

Somewhat related: Maybe also add a newdate() that carries no time
information.
