Seconds vs milliseconds?
JavaScript Date.now() returns ms; many US APIs use seconds — divide or multiply by 1,000 accordingly.
UTC vs US Eastern in logs?
Epoch is always UTC; display applies your browser offset for local debugging.
Year 2038 problem?
32-bit signed seconds overflow in 2038; modern systems use 64-bit — verify legacy embedded devices.
