Net::Time(3pm)						 Perl Programmers Reference Guide					    Net::Time(3pm)

NAME
Net::Time - time and daytime network client interface 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'); DESCRIPTION
"Net::Time" provides subroutines that obtain the time on a remote machine. inet_time ( [HOST [, PROTOCOL [, TIMEOUT]]]) Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC868. The optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be a time value in the same units as returned by time() or undef upon failure. inet_daytime ( [HOST [, PROTOCOL [, TIMEOUT]]]) Obtain the time on "HOST", or some default host if "HOST" is not given or not defined, using the protocol as defined in RFC867. The optional argument "PROTOCOL" should define the protocol to use, either "tcp" or "udp". The result will be an ASCII string or undef upon failure. AUTHOR
