Using the appropriate macros, open file descriptors may be converted into clock IDs and passed toclock_gettime(),clock_settime(), andclock_adjtime(2). The following example shows how to convert a file descriptor into a dynamic clock ID. ...
Example 2: In WSL bash.exe: ssh -v -v -v -v -v <any valid hostname that allows ssh connections>. A large stream of debug messages will be shown, but at the end you will see a message like "%s: chan %d: skip for %d more seconds" where %d is a large positive integer. ...

This makes me wonder how to useclock_gettime()with the first argument other thanCLOCK_REALTIMEin a portable way. For example, if I want to useCLOCK_MONOTONIC_COARSEorCLOCK_BOOTTIME, how do I know that BSD calls themCLOCK_MONOTONIC_FASTandCLOCK_UPTIME, respectively, instead?

For example, Process::CLOCK_REALTIME is defined as :GETTIMEOFDAY_BASED_CLOCK_REALTIME when clock_gettime() is not available.Emulations for CLOCK_REALTIME::GETTIMEOFDAY_BASED_CLOCK_REALTIME Use gettimeofday() defined by SUS. (SUSv4 obsoleted it, though.) The resolution is 1 microsecond. :...
example: using namespace std::chrono; auto t1 = steady_clock::now(); ... auto t2 = steady_clock::now(); double duration_sec = duration<double>(t2 - t1); // seconds as double long duration_ms = duration_cast<std::chrono::milliseconds>(t2 - t1); // msec as long 👍 1 Co...
