After a lot of brainstorming and consulting with some NTP expert I found the following.
NTP expert comment:
Now the question is How to fix the "BROKEN TIMEKEEPING OF LINUX System"?
Can some body help me out?

1) how to show directories in ls command? i went to man ls, and saw this -d flag but doesnt help..
2) say we put this
alias ls='ls -F' in .profile..
how do we let inform .profile that there is a new entry besides restarting the system. thanks.

After rcp -rp from remote host, using du -k to verify the file size but total file size have different size. Check on individual file, file size is correct.
How can I confirm on the file size after ftp?
Pls advise.
Thank you. (15 Replies)
As in
>ls -l *.name
-rw-r--r-- 1 c2s ... file0.name
-rw-r--r-- 1 c2s ... file1.name
-rw-r--r--@ 1 c2s ... file2.name
-rw-r--r--@ 1 c2s ... file3.name
As the example shows, it only happens for some files.
What does the @ mean?
The @ is not described in the man page for ls (3 Replies)
I'd like to create a report that is sent to me via email. It's basically just an ls -l of a directory. However, I'd like to add a column to the end of each file listing that is a numeral - telling me at a glance how old the file is.
For example, instead of this:
$ ls -l
total 9830796... (10 Replies)
Hi All,
Sorry this might be real dummy question. I have been searching from internet and diff manual, but not found any answer
.
By using diff command, how do we display the same content only (from both 2 files in 2 coloumns).
Here is the diff -y output

I can do an ls -l CD* and see the following CDTEST userA RW RW R and I an logged on as userA. But if I do an ls -l the file does not appear. If I do a vi CDTEST it tries to create a new file named CDTEST. If I do a mv or rm I get the message no file of name CDTEST found. Any idea what is going on.... (3 Replies)

However, when i created softlink of that directory and... (3 Replies)

tickadj
tickadj(8) System Manager's Manual tickadj(8)NAME
tickadj - set time-related kernel variables
SYNOPSIS
tickadj [ tick ]
tickadj [ -Aqs ] [ -a tickadj ] [ -t tick ]
DESCRIPTION
The tickadj program reads, and optionally modifies, several timekeeping-related variables in older kernels that do not have support for
precision ttimekeeping, including HP-UX, SunOS, Ultrix, SGI and probably others. Those machines provide means to patch the kernel
/dev/kmem. Newer machines with kernel time support, including Solaris, Tru64, FreeBSD and Linux, should NOT use the program, even if it
appears to work, as it will destabilize the kernel time support. Use the ntptime program instead.
The particular variables that can be changed with tickadj include tick, which is the number of microseconds added to the system time for a
clock interrupt, tickadj, which sets the slew rate and resolution used by the adjtime system call, and dosynctodr, which indicates to the
kernels on some machines whether they should internally adjust the system clock to keep it in line with time-of-day clock or not.
On Linux, only the tick variable is supported and the only allowed argument is the tick value.
By default, with no arguments, tickadj reads the variables of interest in the kernel and displays them. At the same time, it determines an
"optimal" value for the value of the tickadj variable if the intent is to run the ntpd Network Time Protocol (NTP) daemon, and prints this
as well. Since the operation of tickadj when reading the kernel mimics the operation of similar parts of the ntpd program fairly closely,
this can be useful when debugging problems with ntpd.
Note that tickadj should be run with some caution when being used for the first time on different types of machines. The operations which
tickadj tries to perform are not guaranteed to work on all Unix machines and may in rare cases cause the kernel to crash.
COMMAND LINE OPTIONS -a tickadj
Set the kernel variable tickadj to the value tickadjspecified.
-A Set the kernel variable tickadj to an internally computed "optimal" value.
-t tick Set the kernel variable tick to the value tick specified.
-s Set the kernel variable dosynctodr to zero, which disables the hardware time-of-year clock, a prerequisite for running the ntpd
daemon under SunOS 4.x.
-q Normally, tickadj is quite verbose about what it is doing. The -q flag tells it to shut up about everything except errors.
FILES
/vmunix /unix /dev/kmem
BUGS
Fiddling with kernel variables at run time as a part of ordinary operations is a hideous practice which is only necessary to make up for
deficiencies in the implementation of adjtime in many kernels and/or brokenness of the system clock in some vendors' kernels. It would be
much better if the kernels were fixed and the tickadj program went away.
