Reliable TIME and SNTP server for small to midsize local area networks (LAN)
Absolute Time Server is a full-featured time server, which works as windows service and is fully RFC-868 and RFC-2030 compatible. Absolute Time Server acts as a background process, has very low system
resources consumption, and it can be started before user logon.
The short list of Absolute Time Server features includes support for RFC-868 (TIME) and RFC-2030 (SNTP) time synchronization protocols, optimized for performance as NT service (and emulation of NT service for Windows 9x systems), WINSOCK 2 support, low consumption of server resources. In addition to program`s small download size and easy installation, Absolute Time Server starts its job right after installation, without any set-up.
While Absolute Time Server can be and is successfully used as a stand-alone product, it works best when integrated with Absolute Time Corrector, low cost award-winning time synchronization software from FlexibleSoft.
