Unreleased

gnomon:date/0: the current IMF-fixdate as a 29-byte binary, read from a packed small integer in a persistent term and built from fixed-width integer segments so it costs less than an ETS lookup and stays on the caller's heap.
gnomon:format/1 and gnomon:pack/1 for arbitrary Unix times in years 0 through 9999.
gnomon:update/0 and gnomon:clear/0, the clock's write and erase, for a server that runs the clock outside the application.
The gnomon application: a supervisor running one gnomon_clock worker per node, a gen_server that refreshes the value once per second on the system-clock second boundary and erases it on shutdown. The application's stop/1 erases it as well, so the value never outlives the application. On a 32-bit emulator no clock runs and each read computes the date.
EUnit and PropEr tests, including a cross-check against cowlib's cow_date:rfc7231/1.
An erlperf benchmark against the real cowboy_clock, whose binary is off-heap, and against an ETS clock holding an on-heap binary, with results in bench/README.md.
