In addition to this standard NTP service, we also offer an authenticated version of NTP using four time servers which implement the symmetric key encryption method defined in the NTP documentation.
In order to use these servers, you must apply to NIST for an encryption key, which will be linked to the network address es of your system. For more details, please see the authenticated ntp description. The standard does not specify an exact format for the Daytime Protocol, but requires that the time is sent using standard ASCII characters. It returns a bit unformatted binary number that represents the time in UTC seconds since January 1, Conversion to local time if necessary is the responsibility of the client program.
The bit binary format can represent times over a span of about years with a resolution of 1 second. There is no provision for increasing the resolution or increasing the range of years. The strength of the time protocol is its simplicity. Since many computers keep time internally as the number of seconds since January 1, or another date , converting the received time to the necessary format is often a simple matter of binary arithmetic.
However, the format does not allow any additional information to be transmitted, such as advance notification of leap seconds or daylight saving time, or information about the health of the server. However, the time format as specified in RFC has poor error-handling capabilities in general, and many of the client programs that use this format are poorly written and may not handle network errors properly.
Therefore users are strongly encouraged to switch to the Network Time Protocol NTP , which is more robust and provides greater accuracy.
We eventually intend to phase out support for the TIME format on all servers. Another way to synchronize your computer clock is by running software that queries an Internet time server.
NIST provides a free Windows program called nistimebit. Download nistimebit. It uses your Windows time zone and daylight saving time settings, so make sure these are correct. There are several 'Help' links to explain all of the functions. Several programs have been written that can be used to synchronize a computer to NIST. See our list of publishers of computer clock synchronization software for many different platforms. We also have an FTP site with source code for programmers who want to write their own applications.

Set your computer clock via the Internet using tools built into the operating system NIST has established a mailing list Google Group to inform users of status changes of the Internet Time Service. To add additional clocks simply follow these instructions: Choose change date and time settings.

I did reset the clock standerds back to default and the tab appeared, but when I rebooted it disappeared again. Now resetting to defaults has no effect. The guys at the Answer forum sent me here when they heard I was a member of a domain, What does that have to do with this problem? Sync the time on the domain controller and leave it on. Then restart your computer and login. You should pick up the synced time from your server.
I checked the Windows Time service and it is running, and set to automatic Now I'm conserned that the server is not syncing its time to the Internet, How can I get the tab to appear on the server?
