We can't see what's in the box (since closed source), but I personally would be okay with this being a clearly laid out limitation, i.e. having a nice blinking red function comment saying "This integer will overflow if the system is up for more than 50 days, but due to hardware limitations we're unable to properly do X Y & Z with a 64 bit width integer on these subsystems."

If this issue is clearly identified and tested around that's alright, it isn't a huge deal to have to reboot periodically... I'm more concerned this issue is one of those "Oh well, it just... gets a bit off after fifty days - try rebooting it, that seems to fix it."
