Indeed. If anything, this is what you may encounter problems with,
particularly as containers are designed to be, well, not influenced by
their outside environment...

Obvious workarounds (if you need them) that I end up using all the time
here are shell "tricks" like explicitly exporting stuff with env(1):

  - start-container build-script.sh
  + start-container env SOURCE_DATE_EPOCH="${SOURCE_DATE_EPOCH}" build-script.sh

... and throwing a whole bunch of "echo SDE=$SOURCE_DATE_EPOCH" around
is probably the best way to find which barrier is not being crossed.

Best wishes,

Chris Lamb
