Darklands Puzzle #12

A grim iron door blocks your way. Above the door is carved:
ALL STATEMENTS ARE TRUE.
NAME TIFSYN'S FOLK TO OPEN THE DOOR.
On the door are embossed six statements:

1. All full-blooded kobolds love to drink rust wine.
2. Tifsyn is Hoondit's child.
3. Hourly, Tifsyn calls out the correct time from the depths of his lair.
4. Tifsyn is either a gnome, dwarf, or kobold.
5. Hoondit hates rust wine.
6. No gnome is ever truthful.

You ponder, then say...
...Tifsyn must be a dwarf.
...Tifsyn must be a gnome.
...Tifsyn must be a kobold.
