@ivanpauno Updated based on your comments. |

This looks like it needs a rebase, then CI and I think we can get it in. |

Outdated

Found a bug.
std::chrono::duration<DurationRepT, DurationT>(1) depend on user input. This leads maximum_safe_cast_ns isn't fixed value. I will use std::chrono::nanoseconds(1) instead.

I thought this was not a bug, it is intentionally based on user template unit. if i am not mistaken...

If depend on user template unit, there is a below problem.
For the same time, std::chrono::minutes(2562047*60) doesn't throw exception, but std::chrono::hours(2562047) can show exception.
Sorry, wrong place to reply. |
