COH3 Stats - Unix TimeStamp

COH3 Stats is using Unix TimeStamp to mark each day date with the time 00:00:00 UTC.
For example 1683676800 which is May 10 2023 00:00:00 GMT+0000.In JavaScript you can get the timestamp for the current day with the following code:

const date = new Date();
const timeStamp = Date.UTC(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(), 0, 0, 0) / 1000;
