=head1 NAME

Net::Time - time and daytime network client interface

=head1 SYNOPSIS

use Net::Time qw(inet_time inet_daytime);

print inet_time();          # use default host from Net::Config
    print inet_time('localhost');
    print inet_time('localhost', 'tcp');

print inet_daytime();       # use default host from Net::Config
    print inet_daytime('localhost');
    print inet_daytime('localhost', 'tcp');

=head1 DESCRIPTION

C<Net::Time> provides subroutines that obtain the time on a remote machine.

=over 4

=item inet_time ( [HOST [, PROTOCOL [, TIMEOUT]]])

Obtain the time on C<HOST>, or some default host if C<HOST> is not given
or not defined, using the protocol as defined in RFC868. The optional
argument C<PROTOCOL> should define the protocol to use, either C<tcp> or
C<udp>. The result will be a time value in the same units as returned
by time() or I<undef> upon failure.

=item inet_daytime ( [HOST [, PROTOCOL [, TIMEOUT]]])

Obtain the time on C<HOST>, or some default host if C<HOST> is not given
or not defined, using the protocol as defined in RFC867. The optional
argument C<PROTOCOL> should define the protocol to use, either C<tcp> or
C<udp>. The result will be an ASCII string or I<undef> upon failure.
