SyncedCron sending more emails than expected and getTime error?

Not sure why there is getTime no method error below? And when submitting two email sends, I got tons of emails from running it when only two emails are expected 20 and 40 secs apart?

var moment =require(‘moment’);

Meteor.startup(() => {
process.env.MAIL_URL=‘smtp://USERNAME@gmail.com:PASSWORD@smtp.gmail.com:465/’;

var details = {
from: ‘username@gmail.com’,
to: username@gmail.com’,
subject: ‘First Message Subject’,
text: ‘First Text’,
date: moment().add(10, ‘seconds’).unix()
};

var details2 = {
from: ‘username@gmail.com’,
to: ‘username@gmail.com’,
subject: ‘Second Message Subject’,
text: ‘Second Text’,
date: moment().add(20, ‘seconds’).unix()
};

console.log(‘details.date is now :’ ,details.date);
console.log(‘details2.date is now :’ ,details2.date);

FutureTasks.find().forEach(function (mail) {
if (mail.date < moment().unix()) {
Meteor.call(‘sendEmail’, mail);
} else {
// addTask(mail._id, mail);
Meteor.call(‘addTask’,mail._id, mail);
}
});

SyncedCron.start();

Meteor.call(‘scheduleMail’, details);

Meteor.call(‘scheduleMail’, details2);

}); //end of Meteor.startup

Meteor.methods({

sendEmail: function (details) {
check(details, Object);

  // Let other methods calls from the same client start running,
  // without waiting for the email sending to complete.
  this.unblock();

  Email.send({
      to: details.to,
      from: details.from,
      subject: details.subject,
      text: details.text,
      date: details.date
  }); // end of Email model

}, // end of sendEmail definition

addTask: function (id, details) {

  SyncedCron.add({
      name: id,
      schedule: function (parser) {
            return parser.recur().on(details.date).fullDate(); <- THROWS NO METHOD 'getTime' ERROR ????
      },
      job: function () {
          Meteor.call('sendEmail', details);
          FutureTasks.remove(id);
          SyncedCron.remove(id);
          return id;
      }
  });

},

scheduleMail: function (details) {

  if (details.date < moment().unix()) {

      Meteor.call('sendEmail', details);

  } else {
      var thisId = FutureTasks.insert(details);
      Meteor.call('addTask',thisId, details);
  }
  return true;

}
});// end of Meteor.methods
