Operating Systems Linux Red Hat Right way to change time for a RHEL server Post 302752535 by jim mcnamara on Monday 7th of January 2013 06:18:06 AM

If this is a production server:

Code:
1. you should be using ntp services, not manually changing dates
2. When you manually change date/time over any substantial time value 
   you run the risk of breaking things like cron jobs, or application software 
   with services that are time dependent.

answer to your question after you have the date completely correct, you can set time:

Code:
date '+%T'  -s "11:14:00"

note that it uses your example 2 of setting time.

and configure and start ntp.
