There looks to be a date of 2012 etched into the
solder side of the
board...
If this is a mutli-layer board (or could eb a multi-layer board), I think
I'd put the date on an internal layer with clear regions on all the other
layers so it's visible if you shine light through the PCB. That can't be
scraped off.
