@galaxis (64-bit) Time in Userspace
@SoniEx2 Right now I'm more worried about some embedded / appliance crap (that's possibly sitting in some storage as cold standby) with an old openssl and scripts that try to autocreate certificates with 20 years validity on the first startup.
@galaxis someone should make a book How To Derive 64-bit Time From 32-bit APIs And An NTP Client.
