Question

Answer 1

Simple check to see if two time periods overlap:

bool overlap = a.start < b.end && b.start < a.end;

or in your code:

bool overlap = tStartA < tEndB && tStartB < tEndA;

(Use <= instead of < if you change your mind about wanting to say that two periods that just touch each other overlap.)
