Re: [Semediawiki-user] Timeline view for BC dates

[Eric T. B. <eri...@gm...>]

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.
