Comment (by boklm):

 In the branch `bug_19528-v1` in my user repo, we are setting
 `MOZ_BUILD_DATE` (which is used as the build id) based on the Tor Browser
 version:
 https://gitweb.torproject.org/user/boklm/tor-browser-
 bundle.git/commit/?h=bug_19528-v1

 I have not yet tried doing a build using this branch. I can also change it
 to use the version from `browser/config/version.txt` rather than the Tor
 Browser version if that's better.

 Here is the `MOZ_BUILD_DATE` for some values of `TORBROWSER_VERSION`:
 {{{
 $ TORBROWSER_VERSION=7.0 ./build-helpers/get-moz-build-date
 export MOZ_BUILD_DATE=20160208010101
 $ TORBROWSER_VERSION=7.0.1 ./build-helpers/get-moz-build-date
 export MOZ_BUILD_DATE=20160208010201
 $ TORBROWSER_VERSION=7.0.2 ./build-helpers/get-moz-build-date
 export MOZ_BUILD_DATE=20160208010301
 $ TORBROWSER_VERSION=7.0.2.1 ./build-helpers/get-moz-build-date
 export MOZ_BUILD_DATE=20160208010302
 $ TORBROWSER_VERSION=7.0a1 ./build-helpers/get-moz-build-date
 export MOZ_BUILD_DATE=20160108010201
 }}}
