If your computer does not have a direct internet access and you are not required to use proxy server, we recommend you choose "External SNPT Servers".
If you need a proxy server for establishing the Internet connection, we advise you select "External TIME Servers".

higher precision that TIME protocol. "LAN TIME Servers" is left unchanged, so it is compatible with the previous program versions and networks that do not have SNTP servers.

"Connection" section

Proxy server is a special program, which allows LAN users to work with Internet (when only one machine has the "real" IP address). Please contact your network administrator if you're not sure how you're connected, and how to set appropriate options here. Such popular program as ICQ works in LAN using Socks5 protocol.

Type - Now you have to specify your type (Absolute Time Corrector supports SOCKS v4, SOCKS v4A and SOCKS v5 proxies).
Server: Proxy-server address. May be either domain or IP-address.
Examples: proxy.isp.com, 65.166.138.178.
Port: Server port. Usually, it is 1080. Don't confuse Socks5 proxy with http and ftp proxies, which are on 3128 and 3121 ports by default. The program doesn't work through http or ftp proxies.
Login: The name (login) of Socks5 proxy server user.
Password: The password for Socks5 proxy server user.
 

Note

  • Outside of business sites, most users really shouldn't need to set this option.
  • Proxy authorization has nothing to do with the Dial-Up Networking username and password.
  • Check with your site administrator for this information if you need assistance with routing through a proxy server.
  • Please note: only SOCKS v5 proxy supports authentication.
