From b19623e7673a4d6743745382d5d38751b64e011d Mon Sep 17 00:00:00 2001

|
||||
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
