Google Apps脚本触发器：如何获取计时器时间？

Question

var触发器= ScriptApp.getProjectTriggers（）;

for（var i = 0; i

 if (triggers[i].getEventType() == ScriptApp.EventType.CLOCK) {

 // I need to get the timer time of a trigger to show it on a Google Sheet.

 // But I cannot find the detail.

 // Anyone can show me how to do it ?

 // Thanks, Thomason

 }
