Hello Linux Experts,

Perhaps I would like to ask how I can set date in linux ?
For eg, in Dos, we can use

   Current date is 0-03-2002
   Enter new date (mm-dd-yy) : _

So for linux how do we set it ?

Thank you
Derrick Koay

To enter a date for 25th of december at 23:15 do:

date 12252315

or do:

man date

keep in mind that  date  , unlike to DOS' date, just sets the OS' time, the BIOS clock (RTC) remains unchanged.
Also see  man date  and check for the  -u  option.

If you want to st the RTC, see   man hwclock

I strongly suggest you use ntp to set the time.
This automatically updates your clock, using publicly accessible time servers.

2)write to Hardware Clock(BIOS)

thanx for the answer, but what I need is to set both time and date. Paulqna answer is more accurate as I had solved the problem with its way.

answer depends on the questioner's intent:
  - setting time/date in OS only --> date
     paulqna gave the answer
  - setting time/date in BIOS (independent of Linux): --> date -u   or  hwclock
