Hello Ben,



This was due to an oversight on my part: I'd set the epoch for both 

testing and documentation building in the script, expecting that doc 

dates would always be explicit in sources. The 2018-03-08 release fixes 

this, but you can add



     forcedocepoch = false



to your build.lua file to sort the problem for the moment.
