This is more of a “note to self” post. I was trying to do some earnings event analysis and got tripped by this. If you look at NSE’s quarterly earnings broadcast, the ‘broadcast date/time’ they provide lags the time at which earnings are actually announced.

So if you are looking to match up market action with announcements, then NSE’s broadcast time-stamp is no good.
