We just ran into an issue where tar failed to build on one server setup but built everywhere else just fine. It was running makeinfo to regenerate some docs files and makeinfo was too old for the host it was running on. There was no dependency on makeinfo-native as it was not meant to be regenerating the docs. It was being regenerated as a date from a timestamp used in the docs was different in Asian timezones than in the other timezones our builds were being tested in. I added an entry to https://wiki.yoctoproject.org/wiki/TipsAndTricks/ about how this was debugged. As such, lets default to setting and exporting TZ to 'UTC' as was already pioneered by the reproducibile builds work. This makes the builds deterministic.
