What is Unix Timestamp Converter?
Unix timestamps are integers representing seconds elapsed since January 1, 1970 UTC (the Unix epoch). They are used universally in databases, APIs, log files, and programming languages because they are timezone-independent, compact, and easy to compare arithmetically. Human-readable date strings like '2024-03-15 14:30:00' are ambiguous without timezone context — timestamps are not. This converter handles both directions: Unix timestamp to human date and human date to Unix timestamp, with support for millisecond precision and multiple output timezone formats. Use it to decode expiry timestamps from JWTs, interpret database timestamps, debug cron schedules, and convert dates for API payloads.
