+Subject: [PATCH] runtime: use CLOCK_BOOTTIME in nanotime on Linux
+
+This makes timers account for having expired while a computer was
+asleep, which is quite common on mobile devices. Note that BOOTTIME is
+identical to MONOTONIC, except that it takes into account time spent
+in suspend. In Linux 4.17, the kernel will actually make MONOTONIC act
+like BOOTTIME anyway, so this switch will additionally unify the
+timer behavior across kernels.
+
+BOOTTIME was introduced into Linux 2.6.39-rc1 with 70a08cca1227d in
+2011.
+
+Fixes #24595
