[bars] WSJT-X tip

One thing FT-8 is sensitive to is your computer's clock, which has to be
accurately sync'd with a time server. If you are running on Windows, the
default is to update your clock once a week using the NTP protocol and a
Microsoft time server. WSJT-X recommends installing software to update more
often, but that's not necessary. It's easier to use Regedit. The key to
change the auto time sync time interval settings is located at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient

The key name is *SpecialPollInterval *and the type is DWORD. The default
value is 604800 (decimal) or 0x00093a80 (hexadecimal). That number is the
seconds between update. Change the value to 86400 to auto time sync every
day. Don't make it much shorter than that or you risk getting blocked for
swamping the server with requests. This works on all versions of Windows
back to XP.

Windows uses NTP, not SNTP, and you can also change the NTP server it uses
here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters

...in the *NTPServer* key.
