Future time:

Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set."
FIXED.

According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance:

mjh@mjh-desktop:~$ sudo service ntp start
[sudo] password for mjh: 
ntp: unrecognized service

mjh@mjh-desktop:~$ 
mjh@mjh-desktop:~$ sudo apt-get install update

E: Unable to locate package update

mjh@mjh-desktop:~$ sudo service ntp start
ntp: unrecognized service
mjh@mjh-desktop:~$ 

Suggestions?
