Timestamp notes
Unix timestamps represent time relative to 1 January 1970 at 00:00:00 UTC. Seconds may contain up to three decimal places; milliseconds must be whole numbers.
ISO 8601 values require an explicit timezone, such as 2026-11-03T13:30:00Z or 2026-11-03T19:00:00+05:30. Your browser determines the displayed local timezone. Nothing is uploaded.
