Time value on expiry day

So today 17th sept being the expiry, Nifty was trading at 11560 in the morning.
So 11500 CE was trading at 57 (2rs less than intrinsic value) and 11600 PE was trading at 62 (22rs time value).

Why is that call option was not having any time value, and put option was having it ?

Should check with future and not with spot till last 30 mins on expiry day.
