Summary

Story summary

On January 19, 2038, 32-bit Unix time systems will overflow, causing timestamps to revert to negative values.
Experts suggest transitioning to 64-bit time support, which would significantly extend time storage capacity.
Many existing systems still rely on 32-bit time, making the transition complex and risking issues for older programs if they are not updated.
Future problems such as the Year 2184 issue are anticipated as technology evolves.
