Hey ppl, i was wonddering, in mandrake, how to get the clok to display the time in non-military format....hehe thank you im just tired of looking at 18:00 hehe thank you (2 Replies)
Guys could you please tell me which appropriate command is used to set hardware (BIOS) clock so that the system keeps time when it reboots & how it's used. I use Linux
Thank you (2 Replies)
Hey all,
i need a program to get the CPU ticks at certain points of my program. So, i thought about using the clock function, but i'm having a hard time figuring out how it really works. I wrote this simple program to try to understand it but it made me feel more confused:
#include <stdio.h>... (5 Replies)
Hi,
Is there a chance that the clock() call returns 0 eternally???
Using BSD. My RTOS application freezes inconsistently only on particular hosts. When debugging it, I came to see that the RTOS timer does not tick at times. The underlying system call is clock() & it always returns zero when the... (4 Replies)
Hi
We had a AIX box built last year but was set to the correct GMT time, but using DST time zone. In march this year the clocks went forward without issues. (if I remember a couple of weeks early due to the DST zone)
This year we decided to change the clock to the correct time zone before... (0 Replies)
Hi there!!!
Need your help in solving some tricky problems.
Since clock() as such is buggy on SUN OS 5 we have started using gettimeofday() in our RTOS applications based on Solaris 9.
The problems we actually encountered previously were - the applications kind of freeze/hang eternally on... (1 Reply)
Hi all
Hi could anyone tell me how i can set the
Hardware Clock to the System Time, and set the System Time from the
Hardware Clock.
i am using RHEL 4.0.
Thanks in advance. (1 Reply)
I am trying to implement a simple chess clock. It should have the following options: start, stop, reset, read.
Reset will set the time to zero
Start will start the clock
Stop will stop the clock
My problem is that I want that start continues counting
the time from the time it had when it... (6 Replies)

drv_usectohz
drv_usectohz(9F) Kernel Functions for Drivers drv_usectohz(9F)NAME
drv_usectohz - convert microseconds to clock ticks
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
clock_t drv_usectohz(clock_t microsecs);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
microsecs The number of microseconds to convert.
DESCRIPTION
drv_usectohz() converts a length of time expressed in microseconds to a number of system clock ticks. The time arguments to timeout(9F)
and delay(9F) are expressed in clock ticks.
drv_usectohz() is a portable interface for drivers to make calls to timeout(9F) and delay(9F) and remain binary compatible should the
driver object file be used on a system with a different clock speed (a different number of ticks in a second).
RETURN VALUES
The value returned is the number of system clock ticks equivalent to the microsecs argument. No error value is returned. If the clock
tick equivalent to microsecs is too large to be represented as a clock_t, then the maximum clock_t value will be returned.
CONTEXT
drv_usectohz() can be called from user or interrupt context.
