+Subject: [PATCH] Fix build with libc++
+
+In libc++ on 32-bit platforms, int64_t is defined as alias of long long. On 64-bit platforms: long.
+
+On the other hand in definition of std::chrono::duration aliases, that you can find here long long is used
+
+Therefore create custom unit to avoid incompatibility between libstdc++
+and libc++
+
+Upstream-Status: Pending
