Description

Hello!

The launch time of the task displayed on the Spark Stage tab is the UTC time zone, which confuses users in non-UTC time zones. After checking some of the code, it seems that it can be solved by modifying the following code.

File involved

 

Current :

// code placeholder
function formatDate(date) {
  if (date <= 0) return "-";
  else {
     var dt = new Date(date.replace("GMT", "Z"));
     return formatDateString(dt);
  }
}

Updated (example):

// code placeholder
function formatDate(date) {
    if (date <= 0) {
        return "-";
    }
    else {
        let local = new Date();
        let gmtTime = new Date(date.split(".")[0].replace("T", " "));
        let res = new Date(gmtTime.getTime() - (local.getTimezoneOffset() * 60000)).getTime();
        return formatTimeMillis(res);
    }
}
