codechef timelimit problem

recently while solving a problem i just copy pasted a successfully submitted code having run time of 0.1s
and was on to of the list but for me it gave run time of 0.7s . Isn’t it weird? How come same code show different runtimes?
I know it is wrong to copy paste a code but above act was just out of curiosity.

Many times that happens due to server traffic …Happened to me too when I submitted the same solutions 2 times i got the times as 0.4 and 0.2 …And yes it’s weird :wink: …I too was disappointed
