Unix timestamp converter

Convert between Unix timestamps (seconds / ms / µs) and human-readable dates. ISO 8601, RFC 2822, multiple time zones, and 2038 / Y10K overflow checks.

Engineering notes

Unix epoch

  • Zero = 1970-01-01 00:00:00 UTC.
  • Int32 overflow: 2038-01-19 03:14:07 UTC (Y2038). Use int64 going forward.
  • JavaScript Date: ms since epoch, accurate to 100 µs in performance.now().

Common gotchas

  • JS Date.parse('YYYY-MM-DD') → UTC midnight, not local.
  • Postgres timestamptz stores UTC; type matters for DST.
