Time travel in shows

12 Monkeys is the best show at present using time travel as a main plot. I haven't seen 3 of the current  shows on that list. A lot of those earlier shows used time travel as a 'side issue', not as a main plot point. Outlander could be considered in that list too, although it only used it as a basic premise, not an ongoing factor. Timeless looks like it might be the next good one....
