=head1 NAME

NACL::CS::SystemNodeDate

=head1 DESCRIPTION

B<For CMode, the time is now set cluster-wide rather than on a per-node basis,
so switch to using NACL::C::ClusterDate instead.>
(See https://wikid.netapp.com/w/Cluster_QoS/SN_QOS_NTP_FS.)

C<NACL::CS::SystemNodeDate> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. It represents the
state of an ONTAP SystemNodeDate.  A related class is
L<NACL::C::SystemNodeDate|lib-NACL-C-SystemNodeDate-pm>, which represents access
to an ONTAP SystemNodeDate.

=head1 ATTRIBUTES

The individual pieces of data that are part of the  state of the SystemNodeDate
element are the attributes of the SystemNodeDate ComponentState.

    my $SystemNodeDate_state   = NACL::CS::SystemNodeDate->fetch(command_interface => $ci, ...);
    my @SystemNodeDate_states = NACL::CS::SystemNodeDate->fetch(command_interface => $ci, ...);

(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. Called in scalar context it returns only one state object, in list
context it returns all state objects.
See L<NACL::CS::ComponentState|lib-NACL-CS-ComponentState-pm/fetch> for a
more detailed description along with a complete explanation of the options
it accepts.

=item C<NACL::Exceptions::NoElementsFound>

When there are no elements matching the query specified or elements of that type
doesn't exist, then this exception will be thrown.
