Narrative:

Captain of referenced flight has submitted similar text. ATC inquired the length of time it would take to climb from FL310 to FL350 due to conflicting traffic. Captain indicated 3 mins. ATC gave climb to FL350 in 3 mins which was accepted. We did not attain required altitude within 3 mins. More on the order of 3 1/2 - 4 mins. ATC had indicated prior to clearance if we couldn't make it he would give us a heading correction but none was given. ATC made no comment about not making altitude in time allotted. Aircraft that was in conflict was on TCASII and remained outside 10 NM.
