Timeline with BC Dates

There is an open issue on #602956: Implement supported fields as plugins. With this is should be relatively easy to write little plugins in order to support all kinds of input fields.
This should be done first and afterward it would be just a simple plugin to write in order to have support for any special field type.

Same here... For historiographical content, BC dates are indispensable. Subscribing the request.

I notice that dates using CCK Date field do allow for back until 1BC (0001)..

Is it possible to enter the negative values to at least go back until 9999BC?

Please try before asking!
Actually, this would be an issue/question for the date module, not for timeline!
Answering your question: I'm not sure (I'm not the date module's maintainer), but I don't think it is possible. Better: Wait (or contribute in the process) till the plugins for supported fields are out and write your own plugin to support whatever you want.

i have tried a few things such as negative values, but I'm just a user of drupal searching for answers after spending hours hacking at it, I'm not a developer.

thought there might be a known solution out there but I appreciate the reply.

The newest 3.x branch supports plugins based on ctools to be implemented by other (sub) modules. Please check it out to see how to implement support for any kind of data field.

Now you should be able to build a workaround with f.e. classical text fields to support any year spesification, even it wouldn't be supported by the date module. It would be nice if you could share your code here.
Thanks!

Subscribing.... Timeline used to work in version 2.x with cck date fields. Now it appears to only work with Node Date only.

I would very much like to be able to add BC dates to my timelines as well.

It's sad to have to scrap the use of this outstanding module for my current project because it won't permit a BC date. What's particularly frustrating is that there is ONLY ONE BC date, which must be included in the timeline. Ugh!

Has anyone found a workaround with CTOOLS? Would you mind sharing how you did it?

It is now possible to provide new date sources, f.e. a normal text field, that could work, with some validation, to use historical - BC - dates, to the timeline module. This should it make a lot easier for you to get this (and other) functionalities programmed. I think here is "just" some documentation missing.

Please check the related issue on that: #602956: Implement supported fields as plugins
And help testing :-) Thanks.

Hi Xamanu, Thank you very much for your great work on the Timeline module! I am using it on a website on economic history. The webmaster wants to incorporate some BC dates in the timeline. I have downloaded the 6.x-3.x-dev version of the module and the CTools module. Although I am quite experienced in Drupal I do miss some documentation (albeit very basic) to continue working with the timeline. Would you be able to provide me with an outline on how to use the timeline with BC dates? Thanks in advance!

Rocinant, I'm wondering the same thing: it would be great to have some documentation of adding BC dates to a timeline. It sounds as though it's possible, but the path to success isn't clear to me.

Subscribe. Would love to know how to use BCE dates, ideally back to 10,000 BCE. Kevin

Very interested in how to do this in D7.

I have BC dates working for Drupal 6 using the patches for date module here: http://drupal.org/node/273251. I just don't know how to get the field to accept negative numbers bigger than 9999 BC. Any help on altering the length of the date field in the database???

Take a look at http://drupal.org/project/partial_date for Drupal 7 - handles from 999999999999BC to 999999999999AD
