Well, build timestamp and the file set used in the build are not necessaily correlated. One could build the code repeatedly using the same files; each build will have a different timestamp. It is more or less true, though, that it would be difficult to create two builds with different file sets that have exactly the same timestamp.
Version control is really the only method that works reliably. Many, many engineers have westled with the question of how to provide SCM for many decades. So far, we are still using SCM tools to manage version control.

Apologies if this has already been suggested but pressing the FW info
button in NanoVNA 1.03 returns information on the Nano's firmware,
including build 'time'.
Might the build timestamp be usable as a way to tell the different versions
apart?
As a starter, my NanoVNA is a 2-trace 900MHz antenna analyser with build
time May 5 2019 - 08:35:00.
Best regards
