Time flies, timestamps don't Eastern Time (ET) is the default time zone for API responses. If you are a client outside of this time zone, you may need to create a utility to convert ET to your preferred time zone.At KeyBank, we follow the international standard for date and time format (ISO 8601). API responses and error responses include a timestamp in the following format: YYYY-MM-DDTHH:MM:SS. The timestamp returns the date (year-month-day) followed by 'T' to indicate time (hour-minutes-seconds) in 24-hour notation for ET.For example, if you get a response with "Timestamp": "2022-09-15T04:49:03", that means that the action or response was completed on September 15, 2022 at 4:49 a.m. ET.
