Hi,

I'm doing some automated testing that involves very fast file generation 
and recompilation. Platform is linux, GPL 2017 or FSF 7.2. I've observed 
that gprbuild seems to not detect that a file is changed if less than a 
second has elapsed. I will guess here that the timestamp being used has 
second precision. This leads to supposedly up-to-date builds that 
aren't, among other funny effects.

I faintly remember having read about this somewhere, but I'm unable to 
find anything related in web searches. Anyone has experienced this?

Thanks,
Álex.
