isoTimestamp

Creates an ISO timestamp validation action.

Formats: yyyy-mm-ddThh:mm:ss.sssZ, yyyy-mm-ddThh:mm:ss.sss±hh:mm, yyyy-mm-ddThh:mm:ss.sss±hhmm

To support timestamps with lower or higher accuracy, the millisecond specification can be removed or contain up to 9 digits.

The regex used cannot validate the maximum number of days based on year and month. For example, "2023-06-31T00:00:00.000Z" is valid although June has only 30 days.

The regex also allows a space as a separator between the date and time parts instead of the "T" character.

The regex also allows a space before the UTC offset (e.g., " +00:00") to support PostgreSQL's timestamptz output format.

const Action = v.isoTimestamp<TInput, TMessage>(message);

Generics

• TInput extends string
• TMessage extends ErrorMessage<IsoTimestampIssue<TInput>> | undefined
