◆ setNotificationTimestampsForUser()

WatchedItemStore::setNotificationTimestampsForUser	(	UserIdentity	$user,
			$timestamp,
		array	$targets = `[]`
	)

Set the "last viewed" timestamps for certain titles on a user's watchlist.

If the $targets parameter is omitted or set to [], this method simply wraps resetAllNotificationTimestampsForUser(), and in that case you should instead call that method directly; support for omitting $targets is for backwards compatibility.

If $targets is omitted or set to [], timestamps will be updated for every title on the user's watchlist, and this will be done through a DeferredUpdate. If $targets is a non-empty array, only the specified titles will be updated, and this will be done immediately (not deferred).

Since: 1.27

Parameters

UserIdentity	$user
string \| int	$timestamp	Value to set the "last viewed" timestamp to (null to clear)
LinkTarget[]	$targets	Titles to set the timestamp for; [] means the entire watchlist

Returns: bool
