Best Free Time Correction Utility

Anyone know of a time sync which will use the Windows 7 location sensor. I have a built in GPS which gives acurate UTC time and location. The standard Windows 7 Weather gadget picks up the current location from the location sensor and gives local weather.

I saw the tread on IP geo-location, but location sensor is some what more reliable.

On another thought what about picking up th time from a 3g/4g broadband modem in the same way a mobile phone pick's up the current time?

Hm,
lots of interesting suggestions, but i found this article:

So i think the best idea to get time from a NTP server is to work with the original NTP software, which can be downloaded from Meinberg.

Actually there is a cool FREEware utility called SymmTime at: http://www.symmetricom.com/resources/downloads/symmtime/

and it is a 2011 version!!!

Somebody else recommended the utility called Neutron (http://keir.net/neutron.html). It can be configured to run from the command line (we're running it non-interactively too). Just configure the .ini file with the NTP servers you want or leave the existing selection, and change the flags to auto-sync and exit on completion (the other flag is to set the initial NTP server selection). Works brilliantly, even if the clock is completely out.

For microsecond accuracy under Windows 7, use Meinberg NTP software at http://www.meinberg.de/english/sw/ntp.htm and its companion monitor at http://www.meinberg.de/english/sw/time-server-monitor.htm

Be sure to right-click on each install EXE and choose Run As Administrator or it won't install correctly! I also do not install anything into Windows 7 C:\Program Files directory but instead to C:\MyProgramFiles. This seems to resolve a lot of permission issues Windows 7 likes to throw on the Program Files directory.

Here is another simple one--I have been using for some time.. I don't need it on Vista, though, as one is built included with the OS (Internet Time tab via the clock.)

WebTime 2000

NTP pool addresses are useful. A pool address is a virtual cluster of timeservers. There are currently 2000+ servers in the pool.

For example, use "us.pool.ntp.org" instead of "time.nist.gov" to access a pool of 510 time servers in the USA. There are 100's of other pool server addresses all over the world, you can pick a pool closest to you.

For those interested in a simple behind-the-scene time sync program that works in Windows 7, I suggest Time-Sync. It will sync the system clock at start up and at fixed intervals as adjusted in the program's settings. The program is feeeware. You can read more about it and download it from http://www.speed-soft.de/. Be sure to clear the check box "Synchronize with an Internet time Server" in Windows 7 Date and Time applet (Internet Time tab) when using Time-Sync.

Hi Kendall,

Could you please also include limitations i.e. "Too far out of sync" and other time correction problems that these types of programs may have.

I notice one old comment about laptops and PTC batteries that has had no response to date.

I too am searching for a program that will correct time that is months, even years out of date, and that will correct the time and date on start-up.

Yep, same problem with dead PTC batteries and laziness. :-P

I use DS Clock, light and fast

Please review "About Time", it is simple, efficient and works since Windows 98:

I love Dimension4. In fact, to run it in Vista, I was forced to disable User Account Control. But I want to run it in Windows 7 but the UAC problem remains. So I will be looking at other time servers, perhaps those listed by others in your comments.

Take a look at Atom Time - they have been around since Windows 98

I use Karen's Time Sync at

Symm Time is a great product. Free and up to 6 timezones simultaneously. Auto syncs to system clock to any time zone and up to 10 days differential. No year or Month auto sync tho. Customizable clocks, user scheduling updates from 1 munute to 10 days. Lots more features. New version coming in about a week or 2.

This would be perfect for 'Anonymous on Mon, 02/02/2009 - 20:02'

Is there a a similar simple program that automatically adjusts year, month and day, not just day and time? Good for those near impossible to get at tiny unreliable laptop PTC batteries that die when not used for long periods.

PS: Good to see sensible replies here. It's a great site.

Went to other sites and asked same Q? and they go so far off track, like, are you running 60Hz on your laptop, your PTC battery is flat (that's the actual point I, and another here, wish to work around), or, try updating your BIOS. Just need a progam please.

Hello,

I notice the Thinking Man Software site says:
"Commercial users of Dimension 4 v5.0 MUST register by paying US $10 per License."

Personally I've been quite happy with Atomic Clock Sync, which is also free for commercial use.

You can schedule clock syncs from a NIST server at any interval. The programme doesn't seem to give you a choice of protocol, but it will walk you through a quick repair wizard if your computer has stopped syncing. You have to set your time zone manually, but it gives you the option of seeing two extra clocks when you mouse over or click the Window's one in the system tray.

I travel a lot. Do any of these time synch programs (or does anyone know of a program which would) correct the time zone (or notify you that your timezone might have changed) based on IP geo-location?

For my needs, my laptop's RTC does a good enough job of keeping track of seconds elapsed, but when I change time zones, the time is (of course) "incorrect".

Thanks!
