Atomic Clock Service v. 3.1

It is an Internet PC Clock synchronizing application with some useful options (time offset, synchronize periods, time sources choosing, etc). This application uses the list of 19 presetting synchronizing URLs all over the world. The list can be easy enhanced. The application consists of the windows service program and the console program. You can use the consol for options settings, log file viewing and synchronization control. The package can be used as personal computer or office workstation synchronizing solution. The service program can synchronize PC that works under a user login with restricted rights.

PC Atomic Sync v. 4.0

The main idea of the program is to synchronize your PC's clock in the most reliable and resource-saving way.
     The unique Time Offset feature of the program allows setting up your PC clock to gain or to lose for a specified interval. Many our users value this feature greatly.
    Clock in your PC needs to be corrected only several times a month. And it is this fact that defines the way the program works: the program runs when Windows starts, checks whether synchronization has been done this day already, and stops immediately if so. Otherwise the program checks for Internet connection, then tries to synchronize your clock and ends its work if succeeded. So as you see mostly the program is idle and is not wasting resources of your PC. Synchronization is done automatically while you are receiving your e-mail or surfing the web and no actions are to be done by you.
     The program features noteworthy reliability. You can specify the correction period during which the program should synchronize your clock. If it fails user gets a warning notification message.
     This program uses the list of 18 presetting atomic time servers, that are situated all over the world (USA, Australia, France, Germany etc.). They are open NTP (Network Time Protocol) servers. If one of the servers does not work the program chooses another. There is a procedure that tests all servers and shows network delays for them. User can add additional servers to the list. It is really important only for professional users. Any server allows you synchronize your computer with precision less then 0.1 sec with high probability.

Summary:

As a result you don't have to do anything, mostly the program is not wasting resources of your PC but your PC clock always shows you precise time.

Admin Http Time Sync v. 1.1

The main purpose of the program is synchronizing PC clock using HTTP protocol instead NTP or SNTP protocols. Some users and system administrators need such product because they have problems with standard (NTP,SNTP) synchronization. There are firewalls that make such synchronization difficult. The program can be used on the along computer connected to the Internet and in a local network, in home and office.
      It works as NT Service so can be used under user login with restricted rights. The program starts to work immediately after system launching before user login.
      It can be useful for secure using in systems that protected from Internet connection. The program can be used with inside LAN HTTP server without any outgoing connections. The script that shows the server time is delivered with it.
      Other special feature is supporting of bad PC time hardware. If you have fluent time error you can synchronize computer every hour. The program catch jumping time error too. If time jumps the program synchronizes PC clock immediately.
      It has some additional useful options as time offset, synchronize periods, time sources choosing, etc.

OS Non-Proxy Atomic Sync v. 2.9

A standard synchronizing program will not work if NTP (Network Time Protocol) is suppressed by a proxy or a firewall. This synchronizer uses plain access to WWW pages that show standard GMT time. It will work if you have access to Internet Web pages.
The unique Time Offset feature of the program allows setting up your PC clock to gain or to lose for a specified interval. Many our users value this feature greatly. Clock in your PC needs to be corrected only several times a month. And it is this fact that defines the way the program works: the program runs when Windows starts, checks whether synchronization has been done this day already, and stops immediately if so. Otherwise the program checks for Internet connection, then tries to synchronize your clock and ends its work if succeeded. So as you see mostly the program is idle and is not wasting resources of your PC. Synchronization is done automatically while you are receiving your e-mail or surfing the web and no actions are to be done by you. The program uses three different time sources.

GPS Time and Test v. 1.5

It is a PC Clock synchronization program. The program synchronizes PC Clock to the right time using artificial satellites. It is alternative solution to synchronizing with atomic clock using NTP and Internet. The program works in the interactive mode or in background. It uses NMEA protocol. $GPZDA, $ZQZDA or $GPRMC protocol sentences are explored as time source. The program can be used as NMEA and COM port tester. It outputs a port receiving buffer, extracts all NMEA sentences and counts check sum errors. Default protocol version is NMEA 0183. If you want to use this program you need a GPS (Global Positioning System) unit connecting to PC's COM port. The product is free for users of Atomic Clock Service, PC Atomic Sync and OS Non-Proxy Atomic Sync.

Platform:	Windows Vista 64, Vista, XP 64, XP, 2003 server, NT, 2000, ME, 98

User Opinion

Mr. John: What a joy to use! This atomic clock application is one of the best I have seen, very well done and easy to use with loads of features.

Mrs. Ann: This atomic time program was so useful that I sent it to all my friends and co workers. It really is a great software Program. For some ungodly reason Eric has knocked it, Maybe his PC is screwed up. It works just fine.

Mr. Edwards: I've been waiting for this since 2000 since i had a program like this which i lost. Now 3 years later i have found my program!!! Get this NOW!!!

Mr. Dorin Kolabski: On Win2k - outstanding. Super easy and no instructions needed.

Mrs. Collet: This is the best atomic sync program I've ever seen! No spyware signs so far, easy to uninstall (just delete the folder, no regestry entries are created.). It syncronizes with authentic Atomic Time servers for accuracy, and poses absolutely no risk to your. Works great!

Mr. Smith: It worked just as I thought it would. You won't go wrong with these automatic settings. Very useful for setting the day and date on my computer.Try it!

Gardner: Works great with Starband, has a feature where you can have it launch when the computer starts, set the time, then the program closes. Works with Win XP.

Technical notes

PC Atomic Sync allows changing system DST. It is important because some countries periodically change DST rules.
USA example. The current Daylight Saving Time rules represent a change from the past. On August 8, 2005, President Bush signed the Energy Policy Act of 2005, which included the changes in Daylight Saving Time described above, effective in 2007. Prior to 2007, DST began at 2:00 a.m. (local time) on the first Sunday in April, and ended at 2:00 a.m. (local time) on the last Sunday in October. The new rules for DST beginning in 2007 mean an extra four or five weeks of DST each year. There will now be a total of 238 days of DST, compared to a total of 210 days of DST in 2006 under the previous rules, and the U. S. will remain on DST for about 65% of the year.
