I was providing OJT Instruction to a trainee. He was coordinating 4 or 5 estimates to the adjacent ARTCC. The adjacent ARTCC read back the first 4 estimates correctly. When we were coordinating Aircraft X; we coordinated the time and altitude on the strip. The adjacent Center controller hesitated for a few seconds on this particular estimate; and read back a different time. I missed the readback. I do not know why I missed it.In other ATC software flight plan processing; if you try to enter an estimate into the system that was 5 hours in the past; you will get a reject message. Apparently ATOP (Oceanic ATC flight plan processing) does not do this. There should be a logic check about what kind of times they can enter into the system to prevent them from entering wildly inaccurate times. That would help. On my part; I should not place too much faith in a trainee; ever. Complacency happens to Instructors.
I was in training. I coordinated an estimate on an aircraft with the adjacent ARTCC. I coordinated an altitude; time and speed to the Controller. He read back an incorrect time and I did not catch it. I will try harder to listen to all read backs.
A ZMA Controller trainee passed flight estimates to another facility. The receiving facility read back one of the estimates incorrectly and it was not caught by the trainee or the instructor.
