The command "ntpdate" can be used to synchronize time as shown below: bash# ntpdate clock2.redhat.com clock.redhat.com 3 Jan 13:20:59 ntpdate[10754]: adjust time server 66.187.233.4 offset -0.024132 sec Alternate way to set accurate time is to use NTP servers available on internet.

[neo@techpulp ~]# hwclock –show Thu 16 Dec 2010 08:54:38 AM IST -0.966849 seconds [neo@techpulp ~]# Generally the date and time set by "date" command automatically sets time in hardware clock as well. However if you would like to manually synchronize hardware clock to UTC, you can run following command: [neo@techpulp ~]# hwclock --systohc --utc There is another command “hwclock” that can display date and time stored in hardware clock (i.e CMOS clock).

[neo@techpulp ~]# hwclock –show
