\subsection{Detailed Description}
A monotonic clock (aka steady clock) is independent from walltime. 

In particular, while wallclock might jump forward and backward (e.\+g. due to D\+ST), the monotonic clock ticks steadily forward at always the same pace.

{\ttfamily \mbox{\hyperlink{classfz_1_1monotonic__clock}{monotonic\+\_\+clock}}} is a convenience wrapper around std\+::chrono\+::steady\+\_\+clock.
