Sort::Key::DateTime - Perl extension for sorting objects by some DateTime key

  use Sort::Key::DateTime qw(dtkeysort);
  my @sorted = dtkeysort { $_->date } @meetings;

Sort::Key::DateTime allows to sort objects by some (calculated) key of type DateTime.

dtkeysort { CALC_DT_KEY } @array
returns the elements on @array sorted by the DateTime key calculated applying "{ CALC_DT_KEY }" to them.
Inside "{ CALC_DT_KEY }", the object is available as $_.
NOTE: sorting order is undefined when floating and non floating DateTime keys are mixed.
rdtkeysort { CALC_DT_KEY } @array
sorted @array in descending order
dtsort(@array)
rdtsort(@array)
sort an array of DateTime objects in ascending and descending order respectively.
Example:
  my @sorted = dtsort @unsorted;
    
dtkeysort_inplace { CALC_DT_KEY } @array
rdtkeysort_inplace { CALC_DT_KEY } @array
dtsort @array
rdtsort @array
sort @array in place.
mkkey_datetime($dt)
generates string sorting keys for DateTime objects
