Pro Tips
If a timestamp gives you a date far in the future or past, check whether it is in milliseconds (13 digits) when you expected seconds (10 digits) — divide by 1000 to correct.
The Year 2038 problem affects 32-bit systems: the max signed 32-bit integer (2,147,483,647) corresponds to January 19, 2038. Modern 64-bit systems are not affected.
JavaScript's Date.now() returns milliseconds. Most Unix tools and databases use seconds. Always document which unit your system uses.
