請問NTPCLOCK及Atomic Clock Sync問題

[powerrock]

請問各位大大....

1.Ntpclock底下的網路校時設定/立即查詢主機時間...為什麼我都連不到主機？
(tick.stdtime.gov.tw及time.stdtime.gov.tw......等)


2.Atomic Clock Sync 每天總會慢19秒左右...這一定要我們天去Ping一次主機嗎？還是它可以設定規則？


謝謝大大！

試這個看看
watch.stdtime.gov.tw

謝謝...但還是不行...以下三種通訊協定都試過了...

SNTP
Time/TCP
Time/UDP

去國家實驗室(沒講錯吧??)...看看他最新的伺服器是哪個，你沒開防火牆吧...

網路時間傳輸協定（NTP-Network Time Protocol）是由美國德拉瓦大學的David L. Mills教授於1985年提出，是設計用來使Internet上電腦維持相同時間的一種通信傳輸協定。該傳輸協定可以估算出資料包在Internet上往返延遲，並可獨立地估算電腦時鐘偏差，從而實現網路上高精準度電腦校時。


時間伺服器（Time Server）是利用NTP的一種伺服器，通過它可以使Internet中電腦維持時間同步。


NTP是一個跨越廣域網或區域網路的複雜的同步時間傳輸協定，它通常可獲得毫秒級的時間精度。目前北京大學參與到CERNET時間服務體系中，為校內用戶提供最便捷、準確的時間服務


啟動W32Time服務
在預設的狀態下，W32Time服務是在系統啟動的時候自動載入，您可以用系統管理工具或者 Net Time 工具自由的啟動或者停止W32Time服務。

1) 在圖形界面上啟動W32Time服務："控制台-系統管理工具-服務-"中點擊"Windows Time"服務，並且在彈出的對話視窗中點擊"啟動"按鈕；

2) 在圖形界面上停止W32Time服務："控制台-系統管理工具-服務-"中點擊"Windows Time"服務，並且在彈出的對話視窗中點擊"停止"按鈕；

3) 在指令行格式下啟動W32Time服務：使用指令 net start w32time ;

4) 在指令行格式下停止W32Time服務：使用指令 net stop w32time ;
或者

注意：
在WIN2000下，您需要把我們的NTPS配置成W32Time服務外部時間源。您可以在指令行模式下，是用Net Time 工具：
net time /setsntp:IPAddress
注意：IPAddress 是NTPS的IP位址。

win2k下執行：net time /set sntp:ntp.sjtu.edu

我在圖中用了time.windows.com這個時間伺服器，大家使用的時候可以自己選項，我最後會附上時間伺服器列表。
然後執行net stop w32time，再執行net start w32time，使本地機和時間伺服器同步。

有的時間大呵呵，現在時間自己就會變成準確的時間了。家需要多反覆幾次以上2個指令。
對於xp以後的系統，控制台>時間與日期 ...按點擊>.直接貼上
時間伺服器(time server)名單
time.windows.com

Neutron 1.03

Neutron

Version 1.03 - March 12th 2002
------------------------------

Neutron is a very simple and small time synchronizing program that
retrieves the accurate time from one of several specialized time servers
on the Internet. Once the network time has been retrieved the program can
set your computer's clock to match it.

Options in the program enable you to automatically obtain the time from the
time server and set your clock appropriately at program startup. It is also
possible to have the program automatically exit after the time has been set
and so is ideal for placing a shortcut in your Startup folder to sync your
clock when your computer is started.

Neutron uses the standard Time protocol (TCP or UDP port 37). See RFC 868
for more details. The time retrieved from the network time server is given
as the number of seconds since midnight on January 1st 1900. Since the
protocol only allows accuracy down to the second you may not get the most
accurate time possible but it is usually good enough to always be within
about half a second of "true" time. Network latency is accommodated in the
calculations involved in setting your computer clock.

Clicking the setup button ">>" shows you the program options. Clicking the
same button will hide the options.

The setup options allows you to choose the time server that is used by
selecting from a preset list in the dropdown list. You may prefer to use
one that is located nearer your computer for faster responses.

Choose TCP or UDP for the Time protocol to be used. UDP is recommended
because of the lower network communications overhead.

Select whether you want the program to automatically obtain and synchronize
to the network time when you start the program by clicking in the "Auto
sync at program startup" checkbox.

Select whether you want the program to exit after it has synced your clock
time by clicking in the "Exit after time has been synced" checkbox. If you
have this option set, the next time you start the program you can prevent
the program from exiting by de-selecting this same checkbox.


Version 1.00 - Initial Release
Version 1.01 - Wasn't properly taking into consideration Daylight Savings.
Version 1.02 - Typo: "31st" would be displayed as "311st"
Version 1.03 - The midday 12 hour was being displayed as 0 instead of 12.
