From 1af8aabccd65e11caa397c4706353075f623cd01 Mon Sep 17 00:00:00 2001
From: Jo-Philipp Wich <jo@mein.io>
Date: Mon, 8 Aug 2022 23:57:03 +0200
Subject: [PATCH] meta: don't use non-POSIX formats in strptime()
The current strptime() invocations in meta.c use the `%F` format which
is not specified by POSIX and thus unimplemented by some libc flavors
such as musl libc.
Replace all occurrences of `%F` with an equivalent `%Y-%m-%d` format
in order to be able to properly parse user supplied dates in such
environments.
