Considering the amount of devices we have now, and the devices and applications we'll have in 16 years..
I use EPOC time in my own code NOW, a lot... :-/
As I understand it, it seems like it’s mostly software using 32-bit integers that will struggle.
So if you’re writing modern code on a modern runtime running on 64-bit platforms you should be fine (easy to verify by changing your dev environment’s clock).
Out of support, aging 32bit SPARC hosts running 4.6c SAP.
That's production!
replace "int64"
I kid, fixing this will require an even greater amount of effort compared to the Y2K bug considering how many more linux devices have been deployed since then.
