Windows as NTP Time Server
Most consumer devices do not really know what time it is. The hardware inside of them is also somewhat cheap and not very accurate. Even if you manually set the time in a device it would slowly drift out of accuracy. Within a month it could be off by a matter of hours. Therefore, these devices must constantly ask a centralized location for the correct time. NTP is the Network Time Protocol. It is a way for a device to get the current time. Typically, a device like a router has an NTP Server inside of it. So devices can sync with the router. However, sometimes it is handy to have direct control over the NTP server (like for a demo). Windows itself can act as this NTP Time Server, but this is not enabled by default. You must use Vista/7/8/10. To setup Windows as NTP Time Server: Open Notepad and paste: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\TimeProviders\NtpServer] "Enabled"=dword:00000001 Save
