Understanding Limits and Speed of the Export API for Event Data

Hello!!, I want to know more about the export api:

For example I want to download the last 24 hours from a project that is posting millions of events daily using this parameters:

 {
    "project_id": 123,
    "from_date": "2025-02-02",
    "to_date": "2025-02-03",
    "where": "properties['$time']>=datetime('2025-02-02T07:00:00') and properties['$time']<datetime('2025-02-03T07:00:00')",
    "time_in_ms": "true"
}

As you can see I need to collect from 7amUTC to the next day. Thanks for your help
