Not giving accurate usage time: queryEvents is giving a different result from my real usage time (comparing against Digital Wellbeing)

[joseph-ampfer]

I'm testing my app on my Pixel 7 pro and trying to use queryEvents() to get the total screen time of the current day, but it is returning incorrect humanReadableUsageTime. Like for Instagram I get "humanReadableUsageTime": "44m 18s", when in reality it is 1hr 38min. I have the appropriate permissions, and this is how I am using it, setting start time to the beginning of the day and end time to the end of the day (I've also tried current time, no difference):

` // ===================FETCH USAGE STATS======================
async function fetchUsageStats() {

// Get current date
const currentDate = new Date();

// Set start time to beginning of the current day (00:00:00)
const startOfDay = new Date(currentDate.setHours(0, 0 , 0, 0));

// Set end time to the end of the current day (23:59:59)
const endOfDay = new Date(currentDate.setHours(23, 59, 59, 999));

// Convert to milliseconds since UNIX epoch
const startMilliseconds = startOfDay.getTime();
const endMilliseconds = endOfDay.getTime();

const events = await queryEvents(
  startMilliseconds,
  endMilliseconds
);

console.log('================================');
console.log(JSON.stringify(events, null, 2));

let total = 0;
for (let key in events) {
  console.log(events[key]['name']);
  console.log(events[key]['humanReadableUsageTime']);
  total += events[key]['usageTime']
};

let minutesOnPhone = total/60000
const now = new Date();
const elapsedMilliseconds = now - startOfDay;
const totalMinutes = (elapsedMilliseconds / 60000);
const points = totalMinutes - minutesOnPhone

console.log(total);
console.log(Math.floor(minutesOnPhone), 'minutes of phone use');
console.log(Math.floor(totalMinutes), 'minutes in day');
console.log(Math.floor(points), 'total points');

};

//=============CALLING FETCH USAGE ON SCREEN MOUNT=========
useEffect(() => {
fetchUsageStats();
// cleanup
}, []); // Empty dependency array means this effect runs only on component mount
`

Part of my results from the queryEvents: "1": { "isSystem": false, "count": 17, "eventType": 0, "usageTime": 2658844, "eventTime": 1713908897089, "packageName": "com.instagram.android", "humanReadableUsageTime": "44m 18s", "name": "Instagram" },

Any help would be amazing, thanks.
