In reply to message 1 from Prayer Times NYC
As salaam alaykum,
I'm sourcing my data from Islamic finder. you're interested in information on correctness or how to determine the proper times without relying on calculation based on Qur'an and Sunnah, I would strongly recommend reaching out to Shaykh Mufti Mohammed Manir (hadithdisciple) since he is NYC; you may also find an answer on his Q and A YouTube channel, search for Mufti Q&A.
Allah knows best.
