How to change Win XP Internet Time synch

[Ropera]

I like to use the little Internet Time synchronization utility that comes witn windows XP (Start > Settings > Control Panel > Date and Time > Internet Time). It is simple, comes with the OS, and does exactly what I want: synchronizing the computer clock.

The only drawbacks are that, by default, it updates the clock once a week, and that the only two server options available (NIST and Microsoft itself) are busy servers, so synchronization lasts several seconds (10 to 20) when I want to do it manually clicking Update Now.

The following are two registry tweaks to improve the Internet Time synchronization:

To automatically synchronize the computer clock once a day:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient]
"SpecialPollInterval"=dword:00015180

To use a faster public server (in N.Y.) that synchronizes almost instantly as a third option (it does not erase the other two):

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
@="3"
"3"="208.184.49.9"

How to use the code:

Open Notepad

Copy the code

Save as Whatever-you-want.reg (for example: time.reg)

Double click the file

Click yes

Probably been posted before but Heres some more Time Servers

Going on what you have as Number 3 I add # 4 - 8

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
"4"="clock.isc.org"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
"5"="timekeeper.isi.edu"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
"6"="usno.pa-x.dec.com"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
"7"="tock.usno.navy.mil"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
"8"="tick.usno.navy.mil"

[stickfun]

any way to make them the default servers for synchronizing?

nice tip btw

Hi,...
I think that you could make somethink like that.

---------------------------------------------------------------------------------------------------------

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DateTime\Servers]
@="1"
"1"="time.windows.com"
"2"="time.nist.gov"
"3"="208.184.49.9"
"4"="clock.isc.org"
"5"="timekeeper.isi.edu"
"6"="usno.pa-x.dec.com"
"7"="tock.usno.navy.mil"
"8"="tick.usno.navy.mil"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpClient]
"SpecialPollInterval"=dword:00015180

But i like when I "merge" this *.reg, the Internet Time check box, begins/stay active. How can i do that?

thanks

ps - the @="1" makes that internet time address, the default. Edited January 19, 2006 by edusnow
