Category talk:Clocks by time

Return to "Clocks by time" page.

Expansion/new category creationEdit

Please see Commons_talk:Categories#Clocks_by_time. -- User:Docu at 14:57, 27 September 2009 (UTC)

Organization of subcategoriesEdit

<moved from Commons talk:Categories>

If Category:Clocks by hour existed then some of the clock images in Category:Time TBD could be categorized. For example File:Katedra front.jpg shows 01:00 within a few minutes (and because it is daylight, it must be 13:00), File:Florence-Duomo-Clock.jpg shows about 14:14, and shows File:Santa maria del fiore, orologio di paolo uccello.JPG shows 19:28 by my guess (but ignoring parallax). This would be better than the "I give up" Category:Clocks with undefined time. Other names could be: Category:Clocks with time in hours only, Category:Clocks showing time in hours only or Category:One handed clocks by time. -84user (talk) 22:55, 28 September 2009 (UTC)
There is an auxiliary category Time by hour. We could use this one or make categories with less precision. Even if we use it, I think we should have a category for clocks with only one hand. If we work out the parallax question, we could also attempt to determine the minute (I tried at digitus dei).
Personally I didn't take in account when a picture was made, but which time it displays. Times of day (a gallery I discovered today) uses daylight or exif to determine time.
BTW, this is less related to the category creation question, so we might want to discussed is at Category talk:Clocks by time. Feel free to move my comment there. -- User:Docu at 23:29, 28 September 2009 (UTC)

I started a Category:One-handed clocks. -- User:Docu at 15:56, 29 September 2009 (UTC)

After a few additions to that category, I think we do need subcategories for clocks with lower precision. They could still be in Time by hour, but should have other names than the current subcategories (Category:Time 00:00 to 00:59). I'm hesitant about the name e.g. Category:Time approx. 01:00 etc. Sundials could be included there as well. -- User:Docu at 17:33, 30 September 2009 (UTC)
Category:Time between 11:00 and 12:00 could be another name. I started it for now. It can be renamed later. -- User:Docu at 20:10, 30 September 2009 (UTC)
I agree, having subcategories like Category:Time between 09:00 and 10:00 appears to be a reasonable approach to sorting the hard-to-be-precise one-handed clocks. They seem Ok for sundials too, except for any rare sundial that has a precision of one minute. To clarify, we should avoid putting one-handed clocks into categories like Category:Time 09:01, because those are intended for clocks showing times to within a minute precision? -84user (talk) 17:39, 3 October 2009 (UTC)
Yes, except maybe for File:Brixen Dom Fassade.JPG that has two separate clock faces. If there is a minute hand, I would attempt to categorize the clock by minute.
For sundials, maybe 3 o'clock should go into 15:00 rather than 03:00. -- User:Docu at 18:07, 3 October 2009 (UTC)

Sub catsEdit

Having the times in Category:Clocks by time as well as Category:Time 00:00 to 00:59 etc looks rather like overcategorisation to me. Also couldn't Category:Time 00:00 to 00:59 & Category:Time between 00:00 and 01:00 be merged? It's all rather calling out for some form of navigation aid as well... Railwayfan2005 (talk) 21:36, 2 January 2010 (UTC)

Grouping them by hour per above sounds like a sensible idea: I was looking to find out how much of the 12:something were already created, but didn't fancy clicking the "next 200" button (and possibly again, and again) to get to it. -- Deadstar (msg) 15:05, 12 January 2010 (UTC)
There is a difference between Category:Time between 00:00 and 01:00 and Category:Time 00:00 to 00:59. The first is for clocks where the time can't be determined with more precision than up to an hour. The second is an auxiliary category that holds all categories with clocks from 00:00 to 00:59.
I fixed at structure of Category:Time by hour so there shouldn't be any overcat problems any more. We could add Category:9 O'Clock Gun to Category:Time by hour, but it wouldn't fit into Category:Clocks by time. -- User:Docu at 15:44, 12 January 2010 (UTC)
Doesn't that mean that for instance Category:Time 00:05 should lose the "Clocks by time" category, and only exist in the Category:Time 00:00 to 00:59 which should sit prominently in the Category:Clocks by time? -- Deadstar (msg) 10:41, 13 January 2010 (UTC)
It depends what you do with Category:9 O'Clock Gun.
Are there any specific categories/images that are currently hard to find or categorize? -- User:Docu at 10:47, 13 January 2010 (UTC)
IMO 9 O'Clock gun doesn't fit in either the Time category or the Clocks by time category as it doesn't involve a clock displaying time. Or am I now completely missing the point? -- Deadstar (msg) 11:05, 13 January 2010 (UTC)
(Oh, and I can find whatever I need, but I did (for instance) not know that there was a Category:Time 00:00 to 00:59 before it was linked in this discussion. -- Deadstar (msg) 11:07, 13 January 2010 (UTC))
It could fit Category:Time 09:00 to 09:59 as it currently doesn't have a category description.
You might want to look at one or the other subcategory, discover the category descriptions (e.g. at Category:Time 09:43, etc. Try to categorize a few more images. If you feel like it, you can add {{User:Docu/clock}} to your user page. It would nice if we had a Dutch version of Template:Category definition: clocks and watches by time displayed. -- User:Docu at 11:25, 13 January 2010 (UTC)


Err... And what is the use of all these categories? It only seems to be an enormous waste of time... Gertjan R. (talk) 08:38, 10 August 2011 (UTC)

(I just looove this kinda stuff.) -- Tuválkin 17:57, 2 October 2014 (UTC)

Category matching actual time?Edit

Why should photos of 12-hour clocks be categorized in the wrong category if it obvious from the photo that it is not the case? Example: File:Österbybruk 2012 10.JPG where it is easy to deduct from the photo that the time is not in the middle of the night. Would it not be be both more accurate, sincere and transparent to categorize it in the correct category? --Ainali (talk) 21:27, 18 January 2014 (UTC)

Demote some photos as incidentals?Edit

It would be good, I think, to create subcategories for photos where the time display or clock face is not readily visible or proeminent; that way things reusers can focus on time-of-day as the main element of an image while detailed documentation in a busier image is still covered. This would be done for the most crowded categories, of course, like Category:Time 02:05. It I’d retain the following:

and I’d move to a newly created subCategory:Time 02:05 (incidental) the following:

If there would be left less than, say, five images in a category, it would not be split. -- Tuválkin 19:09, 2 October 2014 (UTC)

It's probably impossible to define that objectively without defining some arbitrary threshold of non-clock vs clock area of the image. You've defined some images of church towers with clocks as incidental, others not, so apparently it is not the photographer's intention that matters, but literally the relative area. I'm not too enthusiastic about this, it sounds similar to "historical images of X" categories without a definition of how far in the past "historical" is. Also, five images seems like a far too low threshold to split up a category. 15 or 20 seems like a more reasonable quantity from which to start considering that.
To illustrate how arbitrary these decisions would apparently be, here are two of your stated examples:
On the thumbnails here, barely any size difference is visible, and someone who wants a photo of a clock with that time is better served by cropping the second image as that has far higher resolution. darkweasel94 05:39, 3 October 2014 (UTC)
Fair points. Maybe we should revisit this matter in a few months from now, after these categories become more populated. -- Tuválkin 23:08, 3 October 2014 (UTC)

12h vs. 24hEdit

The current categorisation guidelines over here are that 12h clocks (i. e. nearly all analogue clocks, and the overall majority of clocks presently in the category) are to be categorised as between 00:00 and 11:59. While I totally agree with the idea to judge only by the hands themselves and not by daylight etc. (as that would be arbitrary and unreliable), still this introduces some confusion and extra questions. How about creating dedicated subcategories like Category:Time 03:00 (12h) or something like that? They can then be added as subcategories both to Category:Time 03:00 and Category:Time 15:00.
