That's the first time I have got an answer right today!
With the phrase 'that's the first/second/hundredth time' we usually use perfect tense (let it be past, present or future). Yes, it is possible to use continuous tense, as well, but mostly in spoken English.
☑️ That's the first time I have seen such a pretty woman ✅
☑️ That's the first time I am seeing such a pretty woman (less usual)
