In spite of knowing about this issue in 2038, registering a lot of domains to the affect and hoping I can burst out a lot of contracting work that year, make bank and retire.
I’m assuming by EPOC you’re talking about Unix timestamps? There’s nothing wrong with them if they’re 64-bit.
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).
I use EPOC time in my own code NOW, a lot... :-/
