我的男朋友的手机向我展示为"最后见到22.57点" 。我上次向他谈到20.4 00pm。他告诉我他留在网上，并没有关闭应用程序。
那么"最后看到" 待机是什么？是时候他终于失去了信号或签字 - 或者最后一次积极使用与某人聊天的应用程序？
My boyfriend's phone is shown to me as "Last seen at 22.57 pm". I last spoke to him at 20.40pm. He tells me he stays online and doesn't close the app.
So what does the "last seen" stand for then? Is it the time he finally lost his signal or signed off -- or the last time he actively use the app chatting with someone?
From WhatsApp's FAQ:
"Online" and "Last seen at" are timestamps that tell you whether that your contacts are online, or the last time they were connected to WhatsApp. "Last seen at" refers to the time the contact left WhatsApp. You can also think of this as "Went offline at"
So having the app open would still show you as "Online", but does not mean that any messages are being sent. Note that even then, the timestamp might still be incorrect.
The Whatsapp last seen timing is actually when was the last time the contact was seen online, or last used Whatsapp. It is a time stamp that is generated by the Whatsapp server.
There are actually apps that track last seen timings of contacts, like this one called Spyder. It's pretty cool! It is like an MSN console that shows which of your friends are online right now!
