What It Does

Seen gives a quick status check for another player.

If they are online, you get immediate online confirmation. If they are offline, you get how long ago they were seen and an exact date-time stamp.

/seen playername

Returns either online-now status or last online timing details.

Case	What You See
Player is online	Immediate online confirmation
Player is offline with data	Relative time ago plus exact last-seen date and time
No player data found	No data found message
Player has no stored last-online value	No last-online data message

You must include exactly one player name argument.
If you run /seen without a name, usage help is shown.
The feature can be temporarily disabled by server config, in which case you receive a disabled message.

Q: Can /seen show online players too?
A: Yes. It tells you immediately if the target is online right now.

Q: Why did /seen say no data found?
A: That name has no stored player data the command can use.

Q: Does /seen show both relative and exact time?
A: Yes. You get both in one response when offline data exists.
