okay...
Neo - "If you don't know how to write code, you might want to learn first. Maybe my suggestion was premature for you, since you are only 16 and don't have any formal education in programming or computers, or so it seems.
Are you still in high school? Does your high school have computer programming classes?" - Yes, I'm still in high school. I'm home schooled though so I don't have computer programming classes. Almost everything I know about computers I learned myself. You're right though, I don't know too much programming stuff. I know plenty about building, repairing, and upgrading computers and I've done plenty of that stuff... computer programming wise though... I don't know that much. I did a tiny tiny bit probably a year ago(it was with bash though and I was following commands written down) and what I did I liked. But I don't remember any of it. So, yeah, pretty much everything with computers I know I taught myself. I am willing to do the tutorials on cprogramming.com though and I do plan to do that. I really want to get started in programming though because I'd really like to do Systems Administration.
reborg - Okay,I will definitely do C first then, and I can do LFS(linux from scratch) along with it as well. After I finish learning C should I go for C++?
Just wondering...what is systems integration? I might already know what it is and just don't know the name for it... just wondering though.
Thanks agagin everyone!

CHRONY(1) User's Manual CHRONY(1)
NAME
chrony - programs for keeping computer clocks accurate
SYNOPSIS
chronyc [OPTIONS]
chronyd [OPTIONS]
DESCRIPTION
chrony is a pair of programs for keeping computer clocks accurate. chronyd is a background (daemon) program and chronyc is a command-line
interface to it. Time reference sources for chronyd can be RFC1305 NTP servers, human (via keyboard and chronyc), or the computer's real-
time clock at boot time (Linux only). chronyd can determine the rate at which the computer gains or loses time and compensate for it while
no external reference is present. Its use of NTP servers can be switched on and off (through chronyc) to support computers with dial-
up/intermittent access to the Internet, and it can also act as an RFC1305-compatible NTP server.
USAGE
chronyc is a command-line interface program which can be used to monitor chronyd's performance and to change various operating parameters
whilst it is running.
chronyd's main function is to obtain measurements of the true (UTC) time from one of several sources, and correct the system clock accord-
ingly. It also works out the rate at which the system clock gains or loses time and uses this information to keep it accurate between mea-
surements from the reference.
The reference time can be derived from either Network Time Protocol (NTP) servers, reference clocks, or wristwatch-and-keyboard (via
chronyc). The main source of information about the Network Time Protocol is http://www.ntp.org.
It is designed so that it can work on computers which only have intermittent access to reference sources, for example computers which use a
dial-up account to access the Internet or laptops. Of course, it will work well on computers with permanent connections too.
In addition, on Linux it can monitor the system's real time clock performance, so the system can maintain accurate time even across
reboots.
Typical accuracies available between 2 machines are
On an ethernet LAN : 100-200 microseconds, often much better On a V32bis dial-up modem connection : 10's of milliseconds (from one session
to the next)
With a good reference clock the accuracy can reach one microsecond.
chronyd can also operate as an RFC1305-compatible NTP server and peer.
