According to dictionary.com:
Till and until are both old in the language and are interchangeable as both prepositions and conjunctions: It rained till (or until) nearly midnight. The savannah remained brown and lifeless until (or till) the rains began. Till is not a shortened form of until and is not spelled 'till.
So it's rather more than "some say"
. Look up "till" in your own dictionary and see what it says.
