## Date and Time Formats {#date-and-time-formats}

The value in the Date and Time fields of the API must be expressed in ISO-8601 extended format. It is recommended to use the institution time zone while representing date and time.
Note: Some of the endpoints provide the date timestamp in a non-standard date format 'YYYY-MM-DD HH:MM:SS UTC'. It is returned in the response as a text. For example, `analysis_ts` in the `TOE` and `Analysis` APIs.

The most frequently used date and time formats are as follows:

|          Date/Time Field           |                                Format                                 |
|------------------------------------|-----------------------------------------------------------------------|
| Full date (day, month, and year)   | YYYY-MM-DD                                                            |
| Time (hours, minutes, and seconds) | hh:mm:ss\[.sss\]±hh\[:mm\] or hh:mm:ss\[.sss\]Z                       |
| Timestamp or date/time             | YYYY-MM-DDThh:mm:ss\[.sss\]±hh\[:mm\] or YYYY-MM-DDThh:mm:ss\[.sss\]Z |
