Bug#817925: add "$t ="

[積丹尼 Dan Jacobson]

Package: perl-doc
Version: 5.22.1-8
Severity: wishlist
File: /usr/share/man/man3/Time::Piece.3perl.gz

Please change

           $t->add_months(6);
           $t->add_years(5);

to

           $t = $t->add_months(6);
           $t = $t->add_years(5);

else everybody will think they don't need the "$t ="!
