Yeah, Synaptic doesn't offer any ways to download source packages AFAIK.
The "Software Sources" GUI makes adding PPAs easily, but it pollutes the
/etc/apt/sources.list.d/ directory with tons of 1-line files. Now I
prefer editing sources.list by hand whenever possible.

The "date" in the package version refers to the date the packager did
the "git pull", independently of what commits were done. A "git
checkout" on the closest previous commit would indeed give the same
source tree.
