Synchronize Time with Atomic Clock - TimeSync

TimeSync is a free portable time synchronization tool. It can be used to quickly synchronize your PC's time clock with an atomic clock (NIST Internet Time Service). Multiple NIST Atomic Clock Servers are available to choose from if another one does not respond.

TimeSync | Synchronize Time with Atomic Clock


TimeSync can be used to synchronize the computer clock with a NIST server. This tool has some features and options that users can customize according to their preferences. Here's a breakdown of those features:

  • Atomic Clock Time Syncing: The tool retrieves the current time from a NIST server. It adjusts the PC clock if necessary.
  • Time Data Sources: It can use NIST servers, and it mentions that Windows or the router may also supply the time.
  • User Interface: The time and date are displayed according to the user's regional settings. The tool has a window that shows information about the time synchronization process.
  • Atomic Accuracy: Accuracy is usually within a second.
  • Fallback Time Synching Mechanism: It will try alternative servers if the preferred server is unavailable.
  • Automatic Time Synching: It has an option "/auto" to run from the Windows task scheduler. In "/auto" mode, the window will not show if the clock deviation is under a given minimum.
  • Adjustable Settings: Users can customize the minimum clock deviation for adjustment (default 2 seconds). There's a minimum clock deviation for notification in "/auto" mode (default 3 seconds). Users can set a time check delay in "/auto" mode.
  • Multilingual Support: Multiple language files are available, indicating support for internationalization.

This tool was designed to provide accurate time synchronization for Windows users, and the options provided allow users to tailor its behavior to their specific needs and preferences. The automation feature ("/auto") makes it convenient for scheduled time synchronization without the need for user intervention.
