How do i set time in 24 hour format?

Mon Apr 12 05:17:21 IST 2010

When its 17:17 Here.

How would i change it so that it should show.

The options of the date command vary from OS to OS. This should work as the root user on most systems:
Code:
date [-u] [MMDDhhmm[[CC]YY][.ss]]

-u denotes the time you enter is in GMT or UTC timezone, which may not be the timezone you are actually using.
So, try:
Code:
 
date 04121717

assuming you don't want to change seconds.

This is determined by your locale. See:
Code:
man 1 locale

What do you get for:

Code:
echo $TZ ; date ; date -u

touch /tmp/my_temp_filename
ls -lad /tmp/my_temp_filename
rm /tmp/my_temp_filename

I am amazed that the difference between "date" and "date -u" is not a whole number of hours.

What Operating System do you have?
What Shell are you using?
Are you working in the same timezone as the computer? If not, what timezone?
Are you running a virtual machine or some other weird setup?

My first impression is that the system clock is 12 hours out but we really need to see what timestamp is going on new files.

IST is: India Standard Time (IST) +5.5 hours
so not that unusual. There's 3 seperate timezone that are 30 mins offsets, and at least one thats 45 min offsets
