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 DST), the monotonic clock ticks steadily forward at always the same pace.

monotonic_clock is a convenience wrapper around std::chrono::steady_clock.

Constructor & Destructor Documentation

◆ monotonic_clock()

monotonic_clock ( )
default

Constructs empty clock.

Comparisons with empty clocks and adding durations to an empty clocks are undefined.

Friends And Related Function Documentation

◆ operator-

duration operator- ( monotonic_clock const &  a,
monotonic_clock const &  b 
)
friend

Gets the difference between two clocks as duration
