Jinja2 filter strftime stopped working in salt-ssh 2018.3

[anlutro]

I'm using salt-ssh from a virtualenv and a checked out git repository. It worked fine using 2017.7, but 2018.3 fails because at least one Jinja filter no longer seems to be present:

$ salt-ssh odin state.apply

During handling of the above exception, another exception occurred:
