Byron, thanks for that.  I think I understand your use case. However, 
does this practice assume the build date is close to the date when the 
software version was created?
- For example, I assume you'll merge a git commit to create a new 
software version, and then build an image based on that commit.  In this 
way, the build date correlates closely with the version.
- However, if you build an image from an older commit, or wait a long 
time before building an image, the build date will not correlate closely 
with the version.  This can be misleading and lead to errors in handling 
images.

Is that a concern for you?
