This category contains sites providing software for time servers. As there is no hardware category, many hardware based time servers are also listed here also. Most of these use the Network Time Protocol. Information on that protocol can be found in
Computers/Internet/Protocols/NTP. Client software for synchronizing a computer's clock can be found in
Computers/Software/Internet/Clients/Time. Web sites which provide the current time as well as sites with general information on time can be found in
Reference/Time.
