Loran can do great frequency measurement -- almost as good as GPS. But for timing, it's not so hot. The problem with current Loran is that it doesn't carry a timecode, or mark the second epoch. It's possible to recover 1pps from Loran with a bit of work (the Austron 2100T receiver can do this) but it's not a trivial task, and in any event you need something else to disambiguate the seconds.
