How to fix! Garbled time?

irajjs · 06-23-2012, 04:52 PM

When installing Mandriva 2011 i could not connect to the Internet to be able to use NTP server for time adjustment,also i made a mistake by not checking daylight saving....anyway the time was not adjusted correctly and manual adjusting was useful only for that session! then i copied a "drakclock" into my bin folder and adjusted the time! this worked but whenever i type "at" the output is : Garbled time!
the time is correct now but trying to connect NTP fails due to some errors(i thought that may be NTP sever can fix this problem)...and i want to use "at" command.How do i fix that? please help.

Please provide more information. What errors are you getting in response to what commands? Also, what happens when you use the date command? (See man date for the arguments.)

Hi
[iraj@localhost ~]$ date
Sun Jun 24 21:22:40 IRDT 2012
which is correct..no problem!
[iraj@localhost ~]$ at
Garbled time
..........
when i try to adjust time and date by ntp using a clock widget's date and time adjustment interface This is the error:
Unable to authenticate/execute the action: 7, DBus Backend error: could not contact the helper. Connection error: . Message error: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

This is normal since you are not actually providing any time as an argument. Any NTP or adjtime errors are unrelated.

A few things.

This is how to use the at command:

Code:

echo "/path/to/your/script" | at 23:00

at must have a time or a date-time parameter.

As an ordinary user you cannot adjust the time. Your widget is running on the desktop, hence with your own credentials, not root, and cannot adjust time. You have to be root for that.

If you don't have ntp installed, install it. Configure correct servers in /etc/ntp.conf.

If you want to make a large adjustment to the time, stop the ntp service, run ntpdate <time server name>, and restart ntp.

Hi
I have a weak memory but i think that in previous version(Mandriva2010)i used the command "at" to make some alarms ,reminders...etc..and i think by typing "at" a graphical user interface appeared enabling me to do all these.
.....................
in case of ntp :
[iraj@localhost etc]$ ntp.conf
bash: ntp.conf: command not found
[iraj@localhost etc]$ su
Password:
[root@localhost etc]# ntp.conf
bash: ntp.conf: command not found
[root@localhost etc]# /etc/ntp.conf
bash: /etc/ntp.conf: Permission denied
....................
Here i have another question:
Who denies the permission to root?!

/etc/ntp.conf is not a command; it's just a path statement. That's why you got the permission denied. See this example:

Code:

tuna:~$ /etc/network/interfaces
bash: /etc/network/interfaces: Permission denied
tuna:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
(snip file contents)

Try ls /etc/ntp.conf or cat /etc/ntp.conf.
