Presentense Overview
PresenTense picks up where Windows leaves off
PresenTense software replaces the minimal W32Time utility with significant capabilities for the network user. Shorter time sync intervals for superior timing accuracy, real-time monitoring, loss of time sync alert, support for redundant time sources, and easily accessed record logs all are provided in an intuitive, easily implemented package.
Presentense Details
Microsoft states that the W32Time Service is not designed to provide accurate time sync capability. “W32Time meets the requirements specified by the Kerberos authentication protocol to provide clock values that are loosely synchronized across a network. This service is not designed for use by applications that require greater precision.” —Microsoft article, Windows Time Service
