With the current version of Docker OSX, the timezone files need to be included. Tried a couple of configurations here but it seems the simplest solution for now is to link the files directly e.g.
volumes:
- ./files/password:/root/files/password:ro
- ./files/genesis.json:/root/files/genesis.json:ro
- ./files/keystore:/root/.ethereum/devchain/keystore:rw
- /usr/share/zoneinfo/Australia/Sydney:/etc/localtime:ro
Simplest way Ive found to setup a local devchain is to use ethereum-docker.
