Alpine image is not working

[sbilgil]

Hi there,
I am using duckling as a docker image with debian, and it is working perfectly. But I wanted to use it with Alpine distro. I prepare dockerfile for it. But it got some errors. And i just fix some of them. But now although i have timezone Greenwich at usr/shared/Greenwich and copied it to etc/localtime. (RUN cp /usr/share/zoneinfo/Greenwich /etc/localtime) it keeps giving me error :
duckling-example-exe: /usr/share/zoneinfo/Greenwich: invalid timezone file: no timezone found in OlsonData
It is not accepting OlsonData in Alpine i guess.
