Talk:cpp/chrono/high resolution clock
From cppreference.com
| bool is_steady [static] |
true if the time between ticks is constant and calls to now return values that increase monotonically (public static member constant) |
"the time between ticks is constant". Isn't this always true because member type period already specifies seconds per tick?
- What was meant time span between ticks might be very large or even negative in case the clock is adjusted when is_steady == false. I'll try to describe it in a more understandable way. P12 08:03, 22 December 2012 (PST)
- so member type
periodmay fail to represent the real value of seconds per tick， if is_steady == false? 222.205.6.190 18:24, 22 December 2012 (PST)- Yes. P12 18:28, 22 December 2012 (PST)
Howard Hinnant (the author of chrono) has publicly stated that high_resolution_clock was a mistake: in real world implementations, internally it ends up just being either a steady_clock or system_clock... but it's inconsistent and the developer does not know which it is.
Perhaps we should note that on the page for it?
