DNetTime

DNetTime is a tiny and practical application you can configure to automatically and regularly synchronize your system clock with various time servers available online if you're not pleased with the default Windows settings.

Sync your local time to Internet servers

It gives you the possibility to create and prioritize a list with multiple time-based servers and set the sync frequency. In case the first server is unavailable, the tool skips to the next one, and so on.
Plus, it can be installed as a service to automatically download data and correct your clock even when no user is logged on the computer, provided that you have an active Internet connection.

Prioritize time servers and set the sync frequency

DNetTime gets unpacked quickly and effortlessly, since there are no special options, prerequisite software products, or third-party components involved.
The main configuration panel has a simple design and layout, showing the list with predefined time servers from the Internet. They can be removed and new ones can be added. Unfortunately, the program doesn't implement an option for changing their order in the list, so you must add them in the correct order for prioritization.
It's possible to alter the default synchronization frequency (minutes), sync time on the spot with one click, install the application as a service, remove it from the services list, and view the last sync time and duration. Settings can be restored to default.

Evaluation and conclusion

It didn't put a strain on the computer's performance in our tests, since it needed a low amount of CPU and RAM to work properly. We haven't experienced any stability issues, as it didn't freeze, crash or prompt error messages.
To conclude, DNetTime supplies you with a simple solution for keeping your computer's clock synced to online servers. It's free for non-commercial use.
