A Unix Timestamp is a number that represents the seconds elapsed since January 1, 1970, 00:00:00 UTC (also known as the Unix epoch). It's a universal way for computer systems to record time, used globally across all computing platforms.
Example: Timestamp 1640995200 represents January 1, 2022, 00:00:00 UTC
Important: Unix timestamps are timezone-independent. They represent an absolute point in time. Timezones only matter when converting timestamps to human-readable dates for display purposes.
