There was a regression in GNU date where the time zone was not printed:

It's a little hard to tell, but I think this was introduced in coreutils 8.24 and fixed in coreutils 8.26.

If you run the node-manta test suite against a Manta with a default compute image of 16.1.0, you run into this issue. This ends up true for new deployments, though not the Joyent public Manta.
