    That integral does not have a nice closed form solution. Wolfram Alpha offers one involving the error function: wolframalpha.com/input/?i=INTEGRATE+e%5E((t%E2%88%921)t)+t+dt

Hint: define $$u=t-{1over 2}$$ and split the integral by two. Note that this integral has no closed form and you have to use the definition of Q-function.
