UndefinedError: "dateinfo_delta" not defined

[ja11sop]

Thanks for raising this issue and many apologies for the slow response! The error says, 'dateinfo_delta' is not defined. This should be defined under:

trac/timeline/web_ui.py

lines 244 and 250.

Can you check if the function is defined there? Perhaps you need to do an svn update on your patch. Are you using the latest 0.2 REL patch or the DEV patch?

Many thanks.
