How to use the long-timeout.setTimeout function in long-timeout

pendingAtRemoves--
          if (err) conf.onError(err)
          update()// check the schedule for the next
        })

        // emit the scheduled job
        conf.onEvent(next.event)
      }

      if (conf.is_test_mode) {
        // in test mode they manually trigger execution of currTimeout
        currTimeout = onTime
      } else {
        // Execute the event by milliseconds from now.
        // If it's in the past it will happen on the next tick
        currTimeout = lt.setTimeout(onTime, next.at.getTime() - Date.now())
      }
    })
  }

function schedule () {
    var future = next()
    var delta = Math.max(future.diff(moment()), 1000)

    debug(name + ': next run in ' + ms(delta) +
      ' at ' + future.format('llll Z'))

    if (timer) lt.clearTimeout(timer)
    timer = lt.setTimeout(run, delta)
  }

function runOnDate(date, job) {
  var now = Date.now();
  var then = date.getTime();
  
  return lt.setTimeout(function() {
    if (then > Date.now())
      runOnDate(date, job);
    else
      job();
  }, (then < now ? 0 : then - now));
}

function runOnDate(date, job) {
  var now = Date.now();
  var then = date.getTime();

  return lt.setTimeout(function() {
    if (then > Date.now())
      runOnDate(date, job);
    else
      job();
  }, (then < now ? 0 : then - now));
