will most likely be looking at this comment as your compiler will have |

fired an error below. In order to fix this issue, you have two potential |
||||||
|
solutions: |
||||||
|
|
||||||
|
1. Use gpr_timespec or std::chrono::system_clock::time_point instead |
||||||
|
2. Specialize the TimePoint class with whichever time class that you |
||||||
|
want to use here. See below for two examples of how to do this. |
