Incorrect calculation in "RemindMeLater" code

[jeromeDefReputation]

// If the user wanted to be reminded later, has enough time passed?
        let timeIntervalOfReminder = userDefaultsObject?.doubleForKey(keyForArmchairKeyType(ArmchairKey.ReminderRequestDate))
        if let timeInterval = timeIntervalOfReminder {
            let reminderRequestDate = Date(timeIntervalSince1970: timeInterval)
            let timeSinceReminderRequest = Date().timeIntervalSince(reminderRequestDate)
            let timeUntilReminder: TimeInterval = 60 * 60 * 24 * Double(daysBeforeReminding)
            if timeSinceReminderRequest < timeUntilReminder {
                return false
            }
        } else {
            return false
        }

If the amount of time since the current timestamp and the request timestamp is greater than 0, return true if by 'true' is we can show prompt.
