How Old Am I in Seconds and Other Insights From the C++ chrono Library - Nicolai M. Josuttis - ACCU 2025
---

The C++ chrono library has to solve a surprising number of real-world issues. For example:
How many seconds has a year?
Is February 29 a valid day?
What is right format to specify and print a date?
How to invite to a video call between people in Chicago, Cuba, and China?

Introduced in two steps (basics with C++11 and several extensions in C++20), the chrono library now has approaches to deal with these question in a flexible, powerful, safe, and efficient way.

In this talk we will look at durations, time zones, date formats, calendars, clocks, weekdays, leap years, leap seconds, and how to deal with them right using the C++ standard chrono library.

I promise surprises both about the real world as well as the design and use of this library.

The ACCU Conference is the annual conference of the ACCU membership, but is open to any and all who wish to attend. The tagline for the ACCU is 'Professionalism in Programming', which captures the whole spectrum of programming languages, tools, techniques and processes involved in advancing our craft. While there remains a core of C and C++ - with many members participating in respective ISO standards bodies - the conference, like the organisation, embraces other language ecosystems and you should expect to see sessions on C#, D, F#, Go, Javascript, Haskell, Java, Kotlin, Lisp, Python, Ruby, Rust, Swift and more.The ACCU Conference is a conference by programmers for programmers about programming.
Discounted rates for members.
