+From: "Jason A. Donenfeld" <Jason@zx2c4.com>
+Date: Wed, 27 Feb 2019 05:33:01 +0100
+Subject: [PATCH] runtime: use libc_mach_continuous_time in nanotime on Darwin
+
+This makes timers account for having expired while a computer was
+asleep, which is quite common on mobile devices. Note that
+continuous_time absolute_time, except that it takes into account
+time spent in suspend.
+
+Fixes #24595
