Start a build with Toaster, and check what happens to the ETA we show in the 'Latest builds' section of the project page: it goes up as the build progresses, instead of down. The same happens with the ETA we show in the 'All builds' page. It really looks like what we are showing is the time elapsed since the start of the build, and not how long until the build completes (which is what an ETA is). We need to show the ETA, since what's useful to know is how long until the build will be done.
Merged to master.
Verified.
