time in microseconds

[stevocz]

Hi.
How can i get current time in microseconds but from 1.january.0001. something as .NET MinValue

i found only this solution.
std::chrono::time_point<std::chrono::steady_clock> ts = std::chrono::steady_clock::now();
std::chrono::duration_cast<std::chrono::microsecon ds>(ts.time_since_epoch()).count()+621355968000000 00);
