Talk:Clock synchronization

Introduction

The introduction is biased. Clock synchronization is much older problem than computer science; for example, it led Einstein to some of his theories. The need to have synchronous clocks was a major problem for cartographers and navigators in determining longitude since the 15th century. This needs to be rewritten to reflect a much more general and older heritage Intersofia 12:49, 1 December 2005 (UTC)

This history relates to the development of clocks. Older clocks are not synchronized, they are set. Non computer synchronization of clocks is covered in Clock network for which we have a hatnote link. ~Kvng (talk) 17:26, 19 October 2021 (UTC)

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Clock synchronization. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

• Added archive http://web.archive.org/web/20110609015437/http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=1424575 to http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=1424575

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Please add the following.

HUYGENS and Clockwork Systems

Researchers from Stanford and Google introduced HUYGENS, a probe-based, end-to-end clock synchronization algorithm. HUYGENS is implemented in software and thus can be deployed in data centers or in public cloud environments. By leveraging some key aspects of modern data centers, and applying novel estimation algorithms and signal processing techniques, the HUYGENS algorithm achieved an accuracy of 10s of nanoseconds even at high network load. The findings of this research are the basis for Clockwork Systems enterprise solution.

I have added this paper to the Further reading section. Let's wait for it to develop before adding to the article. ~Kvng (talk) 17:26, 19 October 2021 (UTC)

@Kvng: Thank you for the addition. Could you please clarify what you mean by "wait for it to develop"? I'd like to understand what needs to develop before adding it to the article. Thanks! Kentk12345 (talk) 19:44, 20 October 2021 (UTC)

@Kentk12345: we'd like to see some WP:SECONDARY coverage. ~Kvng (talk) 19:55, 20 October 2021 (UTC)

@Kvng: Would this New York Times article (here is the link without the pay wall) count as a secondary coverage? Thanks! Kentk12345 (talk) 22:06, 20 October 2021 (UTC)

@Kentk12345: yes that's what we're looking for! Do you want to add this to the article or do you need help due to WP:COI or other issue? ~Kvng (talk) 16:52, 21 October 2021 (UTC)

@Kvng: I think you should add it. I believe I would be subject to WP:COI. Thank you for helping a first timer learn the process. I appreciate it! Kentk12345 (talk) 18:25, 21 October 2021 (UTC)

@Kentk12345: Ok, I've added it to my list. ~Kvng (talk) 19:38, 21 October 2021 (UTC)

@Kvng: Great. Thanks so much. Also here is information showing clockwork.io is inspired by HUYGENS. Kentk12345 (talk) 18:27, 26 October 2021 (UTC)

@Kvng: has this information been added? Can this request be closed? Z1720 (talk) 19:14, 24 November 2021 (UTC)

No, I haven't gotten to this yet. ~Kvng (talk) 20:59, 24 November 2021 (UTC)

 Done ~Kvng (talk) 20:49, 29 November 2021 (UTC)

Source on how clocks are Synchronized YouTube Video LiveStream of Stephen Wolfram Answering Questions for Kids and the General Public about Science, Technology, and Mathematics

I found a live stream by Stephen Wolfram on YouTube describing how clocks are synchronized in everyday terms at https://www.youtube.com/watch?v=o7ioy6jVXFM&t=1800s. I was wondering if someone could add this as a source for the article of computer clock synchronization.ScientistBuilder (talk) 21:25, 13 October 2021 (UTC)ScientistBuilderScientistBuilder (talk) 21:25, 13 October 2021 (UTC)

I don't find anything about clock synchronization in this video at the time indicated (1800 seconds). Self-published YouTube recordings are not a particularly WP:RELIABLE source. ~Kvng (talk) 17:26, 19 October 2021 (UTC)

GPS 2

It would be helpful to include information about how GPS satellites are related to how clocks are synchronized and the fact that most computers don't have GPS built into them which means their timekeeping is not perfect but most phones and tablets do a GPS chip and receiver built-in so that they may increase the accuracy of the time-keeping. For more information see the Computer Science Stack Exchange post at https://cs.stackexchange.com/questions/91128/how-do-computers-synchronize-their-clocks-with-the-standard-time. ScientistBuilder (talk) 21:28, 13 October 2021 (UTC)ScientistBuilderScientistBuilder (talk) 21:28, 13 October 2021 (UTC)

Stack exchange is WP:UGC so not a good source. I've improved Clock synchronization § Global Positioning System. Cell phones synchronize their real-time clock over the cellular network and that's a synchronization method that's not (yet) described in the article. ~Kvng (talk) 17:26, 19 October 2021 (UTC)
