Common Mistakes to Avoid

⚠️

Seconds vs milliseconds confusion

Solution: Unix uses seconds (10 digits: 1609459200). JavaScript uses milliseconds (13 digits: 1609459200000). Check length to identify!

⚠️

Not accounting for timezone

Solution: Unix timestamps are UTC. Converting to local time: 1609459200 might show Dec 31, 2020 in PST timezone. Always specify timezone.

⚠️

Forgetting year 2038 problem

Solution: 32-bit signed timestamps max out Jan 19, 2038. Use 64-bit systems or milliseconds format for dates beyond 2038.
