Issue #19850 has been updated by mame (Yusuke Endoh). Status changed from Open to Rejected We discussed this at the dev meeting, and decided not to implement it. Considering frameworks that implement a thread pool, the time when a Thread object is created is not necessarily useful, but could be rather confusing. It would be better for users or frameworks to record their own time at the start of a process. ---------------------------------------- Feature #19850: Get thread creation time https://bugs.ruby-lang.org/issues/19850#change-104592 * Author: ngan (Ngan Pham) * Status: Rejected * Priority: Normal ---------------------------------------- I was debugging some threads hanging issue and thought it would be nice to know how long a thread has been around for. Would there be interest in a `Thread#creation_time` (or some other name) that returns the time when the thread was created? -- https://bugs.ruby-lang.org/
