About Unix Timestamps

Unix Timestamp: Number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch).

Seconds vs Milliseconds: Most systems use seconds, but JavaScript and some APIs use milliseconds. Always verify which unit your system expects.

Timezone Handling: Unix timestamps are always in UTC. When converting to local time, the timezone offset is automatically applied based on your system settings.

Negative Timestamps: Timestamps before January 1, 1970 are represented as negative numbers.
