Denny,

Thanks for your quick response on this.  I haven't personally tried BC dates directly with SIMILE TImeline, however I have seen a few examples (e.g. http://simile.mit.edu/timeline/examples/religions/jewish-history.html).  Any pointers on where the problem may be, or should I prepare to roll up my sleeves and dig into the code?

Temlakos,

Would you mind sharing your version of SMW_DV_Time.php?  It sounds like it may solve my immediate problem.

I'll pulling David Huynh into the loop, since he was the original author of the Timeline. David, does the SIMILE Timeline handle dates BC?

Thank you for that. I don't know where the problem is. AD/CE dates show up just fine, as I have proved on my own wiki. But when I try to make a BC timeline, whether within the Julian Period or before it, I get the same result: nothing renders.

Are you using Fabian Hawahl's original version of SMW_DV_Time.php to store the dates? I built an enhanced version that supports Gregorian, Julian, ancient Hebrew, and modern Hebrew (Hillel II) dates. And I can still get good results with dates having positive years.

The problem would appear to be that /negative/ years (as they render in the XSD-compliant value) throw the timeline script for a loop. Maybe whoever wrote that script never imagined anyone using it to store any sort of date that was outside the Unix Era (1911 through 2038).

Sorry, this is a bug. I can confirm the behavior, and filed the bug.

Hi,

I've started experimenting with the timeline format for BC dates.   Whenever I enter the inline query:

{{#ask: [[Category:Philosopher]]
| ?Birth
| ?Death
| format=timeline
}}

the border of the timeline is present, but nothing renders (only a  gray background).  I have a number of other table and timeline pages  for other date formats and they work fine.  I'm using the following  format for both the Birth and Death Date property (Birth::550 BC  Death::500 BC).  Is there anything special I need to do?

I was running SMW and SemanticResultFormats 1.4.2 earlier this  evening, and upgraded both to version 1.4.5.  I'd hoped that the  latest versions may have fixed some bug, but unfortunately I'm  seeing the same resutls.  Thanks in advance for your help!
