如何在文件中添加时间戳

Question

im试图将时间戳添加到附件文件中。我尝试使用新的Date.getTime来做到这一点，但这似乎不起作用

function init(cash){
    try {
        cash = getFullNumber(cash);
        if(cash <= 0) return;
        var userData = JSON.parse(fs.readFileSync(client.config.dataFolder + "/users/" + currentUser + ".json", "utf8"));
        var arr = getMaxItems(userData, cash);
        if(arr){
            if(arr.length==0){
                client.users.get(currentUser).send("You Need More Cash!");
            } else {
                var text = ahk(arr);
                var file = client.config.dataFolder + "/ahks/" + getFileName();
                fs.writeFileSync(file, text);
                client.users.get(currentUser).send({
                      files: [{
                          //attachment: 'C:/Bot/Currently Running/Cafe Team Bot ver 2.3.0/test.ahk',
                        attachment: file,
                        name: 'opt.ahk'
                      }]
                    });
            }
        }
        //if(str.length>0)
            //client.users.get(currentUser).send(str + "\n`++++++++++++++++++++++++++++++`");
    } catch(err){
        console.log(err);
    }
}
