I typed date on my Ubuntu server tonight at 23:06, this is what it reported from the system clock: Tue May 29 22:56:41 BST 2007 I decided to also check the hardware clock (the one maintained by the CMOS/BIOS) by running hwclock : Tue 29 May 2007 23:04:46 BST -0.258052 seconds Looks like I need to bring my server 'up to date'! To update the system clock use the date command but also pass the date you want the clock set to (you need to be root/sudo to do this): date 05292310 This reads as: "set the system date to the 5th month, the 29th day, the 11th hour (pm) and ten minutes". Remember the date format is American so month first then the day! That sorted the system clock out, so I turned my attention to the hardware clock. This can be easily synchronised with the now correct system clock with the systohc option : hwclock --systohc Below is the hardware clock's date before and after the update compared to the system clock: $ date Tue May 29 23:14:12 BST 2007 $ h
