WebTimeSync
v6.1
The WebTimeSync 6 time synchronizer connects to one of the NIST atomic clock time servers to synchronize your computer`s clock. The Version 6.1 release removes the dependency on COMDLG32.OCX (and is now smaller than ever before), adds server health monitoring, detection of Windows XP and 2003 for event logging, and fixes a long-known bug with the tray icon not properly disappearing. WebTimeSync 6 requires the Visual Basic 6.0 runtimes (MSVBVM60.DLL) and the Microsoft Windows Installer to install.
