When you set a mobile push notification with a scheduled time in the past, it will not be delivered. Push notification systems typically check the scheduled time against the current server time before sending. If the scheduled time is earlier than the current time, the system ignores it or discards it, as it is considered invalid.
For example, if the current time is 3:00 PM and you schedule a push notification for 2:00 PM on the same day, the notification will not be sent because the specified time has already passed.
To ensure timely delivery, always set future times for push notifications. If you need precise scheduling and automation, consider using Tencent Cloud's Push Service, which provides reliable and scalable push notification solutions for mobile applications. It supports real-time delivery and advanced scheduling features to meet your business needs.
