1st Atomic Time keeps your system time accurate by synchronizing it with atomic time servers

Configuring automatic time synchronization

Step #2: Watch the synchronization in progress

<< Back to previous step

In the previous step, we've configured 1st Atomic Time to start on Windows startup, synchronize time and exit. At start of a next Windows session, 1st Atomic Time will load automatically, but it won't show it's main window. Instead, it will go directly into the tray area near the clock and start synchronization. During the synchronization, you'll notice a tray icon animation.

Auto-synchronization animation of the tray icon.

Usually 1st Atomic Time will perform a synchronization and automatically exit. But on the very first step it will show the adjust results dialog, so that you can verify your settings.

First-time auto-synchronization warning.

Also if 1st Atomic Time will detect that a difference between your system time and suggested exact time is more than 30 minutes (or other customizable interval), it will show you the adjust results dialog too.

More than 30-minutes difference detected warning.
