[Solved] How to fix Windows 10 time

This tutorial covers Windows 10, but older versions of Windows are similar.

One solution to fixing it is to synchronize time more often. The default is every 7 days which may not be accurate enough for you. Note that using network time requires a connection to the Internet.

If you have your own NTP (network time protocol server), you can avoid bombarding a public time server with too much traffic. In this example, we use a local NTP server and set it to 1 hour to update time. If you use a shorter interval, the time will be more accurate but cause more network traffic. It is generally good practice to avoid sending too many requests to a public NTP server.

Steps to update Windows time more frequently
1. Open a DOS prompt and type regedit
2. Navigate to registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient
3. Change value to desired interval to synchronize time in seconds.
-- For example, use 3600 for every hour. The default is 604800 which is 7 days. The value is in seconds.
-- Right mouse click SpecialPollInterval
-- Click Decimal for Base
-- Enter 3600 for Value data and click OK

4. (Optional) Point to a local NTP server
-- Open Control Panel and navigate to Control Panel\Clock, Language, and Region[/list]
-- Click Set the time and date
-- Choose the tab Internet Time
-- Choose Change Settings
-- Enter a server name for a network time protocol server (NTP).
-- Check the box "Synchronize with an Internet time server"
-- Click Update now
-- Click OK
