Ntp windows xp

---

Asymmetric latency Network delay which takes longer one way than the other can also have an adverse impact on time accuracy. Ntp windows xp clients resync the system time at regular intervals - between these time syncs, the system will be allowed to run at its normal speed which may mean that it Ntp windows xp either fast or slow - gradually putting the system time out until the next sync takes place.

Removed automatic configuration screens for searching for available servers - not needed with the NTP Pool default servers. Fixed several UI problems. Fixed problems with running the client under limited user accounts in conjunction with the Ntp windows xp Windows Service.

For a system with a failed CMOS battery, the Microsoft SNTP client is pretty much useless. This of course does mean that an incorrect response from the time server can put the system time way out. Unless the user reconfigures the Windows Time Service to start automatically, it will be effectively disabled every time the system is Ntp windows xp. NetTime ensures that it is not setting the system time to an incorrect value by always checking with a second server when configured if the time Ntp windows xp is more than 10 seconds.

NetTime is failing to sync - it reports that it had "Inconsistent responses" If there is a large time difference between the local system and the time returned by the time server, NetTime will automatically check with a secondary server to ensure that the time that it has received is actually valid.

Fixed a problem preventing full uninstallation under certain circumstances. Removed requirement to manually shut down NetTime before installing a new version. Windows Ntp windows xp may be required sometimes due to above bug. Added code to re-show tray icon after Windows Explorer crashes. Fixed an error that caused the program to always check for updates when run as a limited user. Fixed an Access Violation error. Added a workaround for a VCL bug which could prevent the NetTime service from being installed properly in very rare circumstances.

Max Free Run: Indicates how long the program will run for without getting a valid sync before it considers the local time to no longer be accurate. If Time adjustment greater than: The default setting for this means that the local time will be updated regardless of how much difference there is between Ntp windows xp current local time and the time reported by the remote server.

Various other minor fixes Ntp windows xp improvements. Despite the amount of work that has gone Ntp windows xp this updated version, most of the credit for it still lies with Graham Mainwaring. The latest version of NetTime was Ntp windows xp and tested with Borland Delphi 7 Professional. Earlier versions have also been tested to compile successfully with Ntp windows xp Personal Edition of Delphi 7 - if you would like to get into Delphi and make changes to NetTime, you might be able to still find a copy of Delphi 7 Personal Edition that you can download if you do enough searching.

Some changes to improve compatibility with newer versions of Delphi - notes added about upgrading to newer version of the Internet Component Suite. Added option to always provide time when acting as a server. No significant changes since Beta 4. Fixed a few more bugs introduced with Beta 2.

Frequently Asked Questions FAQs. NetTime is failing to sync - it reports that all servers failed: The most common cause of this error is that a firewall is blocking Ntp windows xp Network Time Protocol UDP Port between your system and the servers that NetTime is attempting to use.

NetTime is syncing, but the time is out by an hour - e. As long as Windows is configured correctly, it should automatically handle daylight savings changes for you. Ntp windows xp can also Ntp windows xp your time zone information using the free Microsoft tool: Windows Time Zone Editor tzedit. Can Ntp windows xp configure NetTime to use a proxy server? Most settings should be fairly self explanatory, however some people have asked for clarification on certain settings:.

If Ntp windows xp are using NetTime to act as a time server, you will need to disable the built in Time Service in Windows first. If you want to preconfigure settings that are different to the defaults, they are stored in the registry under:. On 64 bit systems, the above location is remapped to:. Improvements made with this version include:.

The Microsoft SNTP client does have more features available, but they require manual editing of the system registry - something which most users are understandably reluctant to do.

Part of the apparent reason why Graham abandoned the NetTime project was because Windows and XP already include an SNTP Client and a free download was available from Microsoft for Windows NT. Graham Ntp windows xp the Microsoft NTP client as being full featured, however, I strongly disagree with this - I would call the Windows SNTP client very basic - Ntp windows xp user interface has only 2 features - allowing the SNTP server to be changed and a button to attempt an immediate sync.

The speed at which the system time deviates from the correct time depends greatly on the system hardware and also to a certain extent what software is being run. The vast majority of users should find that NetTime more than meets their needs, however if you have specific requirements for very accurate time, I recommend that you investigate installing a full NTP client. A full NTP client has extra features to ensure better time accuracy normally well below 10 milliseconds even between time syncs by adjusting the rate that the system clock runs at.

When upgrading to the new version of the Internet Component Suite, you will need to change the reference to HttpProt in the uses clause of UpdateCheck. If you discover any problems with this version or would like to make a suggestion, please contact me:. NetTime, like most SNTP clients, will generally sync your system time to within milliseconds Ntp windows xp the correct time - often within 10 milliseconds.

Normally, NetTime will only provide time to other systems if it is configured to do and it has successfully synced to an upstream server. If you enable the option to always provide time, you may find that it will give out invalid time to any systems that connect to it!.

Fixed a problem with running on Windows NT Added a balloon tip to the tray icon when run after installation to indicate that NetTime is running. When set to not change time on large adjustment, will now ask user when doing a manual check.

Added option to gradually correct small time errors instead of adjusting the time in one hit - thanks to code Ntp windows xp by Julien Ntp windows xp. Added log file rotation - also thanks to Julien Blitte. Fixed a problem with high CPU usage when a lot of logging activity taking place.

In the end, even with editing the registry settings, the Microsoft client is still just an SNTP client with the limitation of being able to sync with only a single remote server. Like the vast majority of SNTP clients that can only sync with one server, and also most of Ntp windows xp remainder that only have backups for if the primary server fails completely the Microsoft SNTP client has a major problem when it receives a reply with Ntp windows xp vastly different time to what is currently set on the system - the software simply has no way to know which is closer to being correct - either the system time could be wildly inaccurate e.

Added support for Windows Themes. Added option to quit if time adjustment is larger than a set value. Various UI fixes and improvements. Added default servers - thanks to the NTP Pool Project. Added support for the Network Time Protocol "Kiss of Death" packet. Added automatic syncing on additional triggers - e. Added extra information to Ntp windows xp UI to show more details such as the time to the next sync, adjustment for the last sync and offsets and lag for each server queried.

A few other minor improvements. Windows built in time client. Added extra logging information. Fixed an error which could sometimes occur when installing over the top of a previous version.

Alternatively, you can try using the latest trial version of Delphi available from Embarcadero. The latest version has been tested with Delphi XE2 Professional: The current version includes an older version of the Internet Component Suite which is not compatible with Unicode versions of Delphi i.

Fixed a few bugs introduced with Beta 2. Added capability to automatically check for new versions. Ntp windows xp button to view log within NetTime. Intervals can now be entered with units instead of only as a number of seconds.

For Windows XP, in order to prevent the Microsoft SNTP client from setting the system time to a wildly incorrect value, Microsoft made the design decision that their client would only update the system time if the server response was within 15 hours of the current system time.

Previous versions as well as the source code can be downloaded from the SourceForge project page. Note: When upgrading from a previous version, you will need to shut down both the NetTime Service as well as the Tray Icon before running the installer. If you uninstall the old version first, you will need to restart your computer before starting the new installer.
