Overview

Sellers may see Error 6000 when Amazon rejects a date‑time entry because the time‑zone segment does not match the ISO 8601 specification. The issue appears during manual listings, bulk feed uploads, or API calls, and it can halt processing of large batches. Fixing the format prevents unnecessary delays and keeps inventory and pricing updates flowing smoothly.

Key Points

• Error 6000 is a formatting fault — It is raised only when the time‑zone portion of a date string is malformed, not because the calendar date itself is wrong.
• Including a time zone is optional but safer — Omitting the offset lets Amazon apply its default, yet adding a correct numeric offset eliminates ambiguity across regions.
• ISO 8601 is the mandated pattern — All timestamps that contain a zone must follow the YYYY‑MM‑DDTHH:MM:SS±HH:MM layout.
• Offsets are expressed relative to GMT — Positive values indicate hours ahead of Greenwich Mean Time, while negative values show hours behind.
• Common triggers are abbreviations and missing colons — Using “PST”, “EST”, or writing “-800” instead of “-08:00” will instantly generate Error 6000.

How the ISO 8601 Date‑Time Format Works

1. Compose the date segment — Write the year, month, and day in four‑digit, two‑digit, two‑digit order, separated by hyphens (e.g., 2023‑11‑05).
2. Insert the “T” separator — Place a capital “T” after the date to signal the start of the time component (e.g., 2023‑11‑05T).
3. Add the 24‑hour time — Provide hours, minutes, and seconds in two‑digit groups, separated by colons (e.g., 14:30:45).
4. Attach the GMT offset — Append a plus or minus sign followed by two‑digit hour offset, a colon, then two‑digit minute offset (e.g., -05:00 for U.S. Eastern Standard Time).
5. Resulting full string — Combining all parts yields a compliant timestamp such as , which Amazon will accept without raising Error 6000.
