Possible bug with now=undefined

[cama]

in session.js:

let clearOldSessions = co(function* () {
let not = new Date(); //possible bug with now=undefined, I guess it should
be 'now' here :)
let sessionsSize = yield client.hlenAsync("sessions");
let sessions = yield client.hgetallAsync("sessions");
for (senderId in sessions) {
let data = JSON.parse(sessions[senderId]);
if (Math.abs(now - data.lastUsed) > maxSessionAge_ms) {
client.hdelAsync("sessions", senderId);
}
}
let sessionsSizeNow = yield client.hlenAsync("sessions");
console.log('Session Size ' + sessionsSizeNow + ' items. Removed ' +
(sessionsSize - sessionsSizeNow) + ' items');
});
