old tzdata version is unavailable

I had to use 2019a-r0 to get this working. Version is hardcoded at https://github.com/hpaolini/tiny-nvr/blob/master/Dockerfile#L32

Is this with alpine:3.8? Can't seem to replicate the issue with the default Dockerfile.

You could always try passing TZDATA_VERSION=2019a-r0 as an environment variable (with -e) during the docker run. You might have to re-build the cache for the container, though.
