Astro::Nova::HMS - Perl representation of a libnova ln_hms (hours, minutes, seconds)

  use Astro::Nova qw(functions ...);
  my $date = Astro::Nova::HMS->new();
  $date->set_year(...);
  # ...
  print $date->as_ascii(), "\n";
  my @members = $date->get_all();

This class represents a libnova ln_hms struct. The struct has the following layout:

  ln_hms {
    unsigned short  hours
    unsigned short  minutes
    double          seconds
  }

Constructor returns a new Astro::Nova::HMS. Optionally takes key/value pairs for setting the struct members. Extra arguments are ignored. Uninitialized struct members are set to zero.

Get or set any of the class attributes. (See list above)

Returns all members as a list.

Sets all members. Takes a list of values which must be in the order shown above. Any missing values are ignored, undefs are skipped.

Returns a human-readable ASCII table of the date information.

Returns a list of all members in order.

Convert to degrees or radians (returns a number).

to_dms Converts to Astro::Nova::DMS (degrees, minutes, seconds).

When called as a class method, creates a new Astro::Nova::HMS object from the given degrees/radians value or Astro::Nova::DMS object.

When called as an object method, sets the current object's state instead.
