# Date and time

> How dates and timestamps are formatted in the API.

## Overview

All dates and timestamps in the Trace Finance API use **UTC** in ISO 8601 format. No other timezones are accepted or returned.

## How it works

### Format

```text theme={"theme":"tokyo-night"}
yyyy-MM-ddTHH:mm:ss.SSSZ
```

Example: `2026-04-22T20:00:00Z`

| Component | Description                     | Example |
| --------- | ------------------------------- | ------- |
| `yyyy`    | Four-digit year                 | `2026`  |
| `MM`      | Two-digit month (01–12)         | `01`    |
| `dd`      | Two-digit day (01–31)           | `15`    |
| `T`       | Date/time separator             | `T`     |
| `HH`      | Hours in 24-hour format (00–23) | `14`    |
| `mm`      | Minutes (00–59)                 | `30`    |
| `ss`      | Seconds (00–59)                 | `00`    |
| `.SSS`    | Milliseconds (optional)         | `.000`  |
| `Z`       | UTC timezone indicator          | `Z`     |

## Examples

A resource creation timestamp:

```json theme={"theme":"tokyo-night"}
{
  "createdAt": "2026-04-22T20:00:00Z"
}
```

Filtering by date range:

```bash theme={"theme":"tokyo-night"}
?filters=and(createdAt[gte]=2026-04-01T00:00:00Z,createdAt[lte]=2026-04-30T23:59:59Z)
```
