i was looking for something along these lines a few years ago. here's a discussion which, i think, represents the current state-of-the-art (it's not much!):

http://old.nabble.com/Utility-to-read-SMPTE-LTC-"audio"-time-code-td22937033.html

ltcsmpte is here:
http://ltcsmpte.sourceforge.net/

if you look at the svn repository, you'll see jltc, which is an example jack app to read LTC and display SMPTE (and, i think, control JACK transport). i haven't recently needed any such thing, so i'm not sure what the current usability of this tool is. it's likely that there's "some assembly required"!

i don't know of anything else under linux for this sort of thing.

cheers!
