Date and time formats

Date and Time Format

Dashdoc uses the ISO 8601 standard for all date and time fields. Depending on the context, the format can include a date, a time, or both.

All date-time values must be valid ISO 8601 strings.

Accepted formats

• Date only: yyyy-mm-dd Example: 2025-06-05

• Date and time (UTC): yyyy-mm-ddThh:mm:ssZ Example: 2025-06-05T14:30:00Z

The trailing Z indicates that the time is expressed in UTC. When using time zones, only UTC (Z) is currently supported.

• Time only: hh:mm Example: 14:30 Only for time specific field

Common Errors

• Invalid format Dates or times not following the ISO 8601 standard will be rejected. Example of invalid formats:

  • 05/06/2025 (should be 2025-06-05)

  • 14:30:00 without a date or timezone (use 2025-06-05T14:30:00Z)

• Missing timezone in datetime When providing both date and time, the string must end with Z to indicate UTC. Incorrect: 2025-06-05T14:30:00 Correct: 2025-06-05T14:30:00Z

• Hard coded time zones Do not include time zone offsets like +01:00. If you do, every time there is a time change, you will need to update your code manually.
