I am using aSmack library to communicate with remote xmpp server. I am able to send/receive messages, but I want to get timestamp of incoming message.
Could you tell me please, is it possible at all? Because I can't find anything about this question.
Thanks in advance
Timestamp is not part of the regular messages. Therefore you cannot extract it.
There is a spec (as mentioned by @Dmitry), but this only applies to specific types of messages. Typically those that are NOT realtime, such as offline and publishing the last pubsub message of a node when a new subscription is created. These are messages with an inherent delay built into them.
