Bug #66358 for TimeDate:

Thu Mar 03 13:15:58 2011 MGI [...] cpan.org - Ticket created

With an date specified incompletely, strptime sets some fields to undef, which Date::Format::strftime doesn't accepts as input. Setting the fields instead to 0 would make the two functions more consistent. Example under the debugger): DB<10> p $ts 1-Jan-2009 DB<11> @bits = strptime($ts) DB<12> x @bits 0 undef 1 undef 2 undef 3 1 4 0 5 109 6 undef DB<13> p strftime(q(%Y-%m-%dT%H:%M:%S%z), @bits) Use of uninitialized value in sprintf at /usr/lib/perl5/site_perl/5.10/Date/Format.pm line 208, <GEN1> line 893. at /usr/lib/perl5/site_perl/5.10/Date/Format.pm line 208 ... 2009-01-01T00:00:00+0000 DB<17> for(@bits){$_=0 unless $_} DB<18> x @bits 0 0 1 0 2 0 3 1 4 0 5 109 6 0 DB<19> p strftime(q(%Y-%m-%dT%H:%M:%S%z), @bits) 2009-01-01T00:00:00+0000

this is intentional. strptime returns undef for fields it does not know the value for. and strftime needs to know all fields. If you want to use incomplete dates, you need to fill in those fields any guess TImeDate would do would be wrong for someone
