Message-ID: <20090310112240.GC1337@ucw.cz> Date: Tue, 10 Mar 2009 12:22:40 +0100 From: Pavel Machek <pavel@....cz> To: Christopher Brannon <cmbrannon@....net> Cc: linux-kernel@...r.kernel.org Subject: Re: [PATCH] /dev/time for Linux, inspired by Plan 9 Hi! > Under Plan 9 from Bell Labs, one queries or sets the system clock by > reading or writing text strings to a special file named /dev/time. > I implemented such a facility for Linux. A read of /dev/time produces > four decimal numbers: epoch seconds, nanoseconds since start of epoch, > jiffies since boot, and jiffies per second. Writing a decimal > number to Jiffies are strange... and I guess time should be exported as 123.456 (seconds . fractional part). That way we are not limited to nanoseconds... Same interface can be used for setting precise time... -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
