What method will allow you to find out when a person wrote a message the last time (VK)?

Question

API

More than once I saw how in many VK bots they use such a command, where some information about the user is shown and one of the items is the "last message" and the time when the person wrote his last message in this conversation, I wondered where the bots take this information, the fact that they record every message and time in the database is somehow hard to believe, but the method is quite.
Tell me (if there is) such a method.
