High-precision timing in Windows, cont.

Building on what I found earlier, here are some more attempts to make a high precision, high accuracy, high performance timer in Windows.

This link explains another timer, and provides BSD-licensed code.

ByteFusion makes a proprietary timer.

SourceForge has a project called fasttime, but it doesn't support Windows.

Fasttime has a sister project, TSC-I2, which has some nice details.

Here is the documentation for the Windows NTP client, w32tm, the Windows Time Service.

An MSDN blog indicates that the Windows Time Service is intended to keep sync only to the extent that Kerberos requires, and cannot maintain sync down to the second boundary.
