Recreational/hobby UAS pilot reported flying during an active Temporary Flight Restriction (TFR). Once they learned of the TFR the pilot exited the airspace by landing.

Narrative

I was flying drone within 3 miles of the sporting event at XA:10; the game started at XB:00; I had lost track of time and didn't realize I had violated the time restriction. I was flying near my location and was not trying to fly near stadium. This was a total unintentional violation of the airspace and I will be more diligent in the future of any event going on within the proximity of an event of the stadium.I am adding this report in addition to one filed to add information that I forgot to include. I was flying my drone near my residence in ZZZ which is within a mile proximity of the stadium. I was not flying with intent of going near the stadium; I was; however; within the restricted area when it went hot [Temporary Flight Restriction (TFR)]. I lost track of time and didn't realize that I was within the 1 hour of game time. The time was XA:10 and the game started at XB:00. I can say that this was an absolute learning event regarding the fact that I had not made myself acutely aware of the time of the restricted airspace being activated while I was flying my drone. I was also surprised that my drone software didn't give me an alert to the airspace issue. I thought that the DJI drones were programmed to alert the user if it was near restricted airspace. I have had the drone for quite a while but am not a very active user of it. I am sorry for the incident and can say it will not occur again.
