- From 83b989ecee478be083db8dc0cc7a5387615bd3cb Mon Sep 17 00:00:00 2001
- From: Andrey Semashev <andrey.semashev@gmail.com>
- Date: Wed, 31 Jul 2019 16:28:05 +0300
- Subject: [PATCH] Added support for utimensat for better POSIX.1-2008
- compliance.
-
- POSIX.1-2008 marks utime as obsolete and replaces it with utimensat.
- uClibc-ng has an option for removing utime, including the corresponding
- header.
-
- Closes https://github.com/boostorg/filesystem/pull/115.
