Description Joshua Lock 2017-03-17 15:16:12 UTC 
Locale and Timezone settings of a shell in which builds are performed can affect the build output in various ways[1][2], adding non-determinism to the system when building on machines with different TZ settings.

We should export a consistent TZ and locale to the environment in which builds are performed in order to improve the determinism of our build output.
