使用percolate：synced-cron软件包，我正在尝试安排在将来的特定时间发送电子邮件。我将未来的任务插入到数据库中，但是我收到此错误Exception in setTimeout callback: TypeError: Cannot call method 'getTime' of undefined
db.future_tasks.find({}).pretty()

我尝试将日期作为字符串，但没有区别。如果我真的尝试通过电子邮件发送任务（没有SyncedChron），如：
Email.send({
from: details.from,
to: details.to,
subject:new Date(),
text: details.date
//date: details.date
});
我明白了：
TypeError: Object Wed Jul 22 2015 15:24:46 GMT-0400 (EDT) has no method 'replace'
