[*publishedon*] returning 0 in Evo 1.0.13

Hi, I'm having a strange issue with the [*publishedon*] and [+publishedon+] tags in Evo 1.0.13. Testing on two different stites (on different servers), [*publishedon*] and [+publishedon+] are returning 0 for some published pages. On first publishing a page (ie. right-click and publish) they do seem to work correctly, outputting a timestamp. However, on re-editing the page and resaving, [*publishedon*] and [+publishedon+] change to return 0.

Testing an older 1.0.12 site, the publishedon tags do continue to ouput the correct publishedon time after re-editing and re-saving the page.

Has anyone else noticed this problem, and might it be related to any chnages in 1.0.13?

Thanks

There is a bug in this commit.

publishedon and publishedby fields are replaced by literal 'publishedon' and 'publishedby' values instead of integers when you save a document without changing its published state. This causes an error if MySQL runs in strict mode and erases field contents in traditional mode.

Should be fixed here:

Many thanks, this fixed it.
