What is the output of these shell commands? cmp /usr/share/zoneinfo/America/Adak /app/zoneinfo/America/Adak You seem to be indicating that these files are identical but I suspect they're not. If they're not identical, please send the output of these shell commands: od -t x1 /usr/share/zoneinfo/America/Adak od -t x1 /app/zoneinfo/America/Adak I'm reluctant to look at Docker images as they are complicated beasts. It would be better if you could isolate your problem to a short Go program that illustrates the issue.
