-From: "Jason A. Donenfeld" <Jason@zx2c4.com>
-Date: Wed, 27 Feb 2019 05:05:44 +0100
-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
-
-Change-Id: I7b2a6ca0c5bc5fce57ec0eeafe7b68270b429321
