Why do you think it is a bug? .count() is really just raw units, the old steady_clock wasn't really steady and had microseconds resolution, the new one (mangles differently; and system_clock too) both have nanosecond resolution. I guess you want to use other interfaces than .count() if you want to transform it into seconds, microseconds, nanoseconds etc. Hmmm. Alright. I was wondered because 4.8.0-6 had such "small" numbers and out of the sudden they were that big. And the cppreference had also the small numbers. Thats why I thought it is a bug. Thanks for your answer. Hey Marcel! Yes, the default resolution of the system clocks changed (for the better, IMHO.) That's why you are seeing bigger numbers. As Jakub stated, this is a feature, not a bug. For typed time values, use c++11's std::duration type. That way you as a programmer can explicitly state the resolution you require, along with the actual value, so that conversions to other resolutions are sane. Perhaps I should note the change in default clock resolution in 4_8/porting_to.html. -benjamin I'm going to edit this subject so that it's more descriptive. This message is a notice that Fedora 19 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 19. It is Fedora's policy to close all bug reports from releases that are no longer maintained. Approximately 4 (four) weeks from now this bug will be closed as EOL if it remains open with a Fedora 'version' of '19'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 19 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
