Could someone explain the difference in meaning between these two forms of conditional?
1.If I had time, I would be there.
2.I would have been there if I had time.
The first refers to the present moment, the second to a time in the past.
(in the second case "I would have been there if I had had time" would seem more common, however, referring to a specific instance; the use of the simple past in (2) implies that your not having time was a more or less continuous state rather than being specific to one event or instance)
