=head1 NAME
FS::h_cust_svc - Object method for h_cust_svc objects
=head1 SYNOPSIS
=head1 DESCRIPTION
An FS::h_cust_svc object represents a historical service. FS::h_cust_svc
inherits from FS::h_Common and FS::cust_svc.
=head1 METHODS
=over 4
=item date_deleted
Returns the date this service was deleted, if any.
=cut
sub date_deleted {
my $self = shift;
$self->h_date('delete');
}
=item label END_TIMESTAMP [ START_TIMESTAMP ] [ LOCALE ]
Returns a label for this historical service, if the service was created
before END_TIMESTAMP and (optionally) not deleted before START_TIMESTAMP.
Otherwise, returns an empty list.
If a service is found, returns a list consisting of:
- The name of this historical service (from part_svc), optionally localized
- A meaningful identifier (username, domain, or mail alias)
- The table name (i.e. svc_domain) for this historical service

# Parameters to _label:
#
# 1: the cust_svc method we should call to produce the label. (svc_label
# and svc_label_long are defined in FS::cust_svc, not here, and take a svc_x
# object as first argument.)
# 2, 3: date range to use to find the h_svc_x, which will be passed to
# svc_label(_long) and eventually have ->label called on it.
# 4: locale, passed to svc_label(_long) also.
#
# however, if label is called with a locale only, must DTRT (this is a
# FS::cust_svc subclass)

=item h_svc_x END_TIMESTAMP [ START_TIMESTAMP ]
Returns the FS::h_svc_XXX object for this service as of END_TIMESTAMP (i.e.
an FS::h_svc_acct object or FS::h_svc_domain object, etc.) and (optionally)
not cancelled before START_TIMESTAMP.
