Ntp not updating system clock
Windows has an automatic time synchronization feature to keep your computer’s clock accurate, but unfortunately it is scheduled to only run once a week.
First of all, click the Settings button on the program.
After installing Time-Sync, by default it is configured to run at Windows startup and automatically performing a time synchronization when the service is started. At the Settings tab, you can configure to enable the event logging and change the update interval.
