Date and time

How dates and timestamps are formatted in the API.

Overview

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

How it works

Format

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:

{
  "createdAt": "2026-04-22T20:00:00Z"
}

Filtering by date range:

?filters=and(createdAt[gte]=2026-04-01T00:00:00Z,createdAt[lte]=2026-04-30T23:59:59Z)
