41 /* If you are trying to use CompletionQueue::AsyncNext with a time class that
42 isn't either gpr_timespec or std::chrono::system_clock::time_point, you
43 will most likely be looking at this comment as your compiler will have
44 fired an error below. In order to fix this issue, you have two potential
45 solutions:
46
47 1. Use gpr_timespec or std::chrono::system_clock::time_point instead
48 2. Specialize the TimePoint class with whichever time class that you
49 want to use here. See below for two examples of how to do this.
