Support KB3381 will apply for this issue.

  1. Log in to the command line.
  2. To change the operating system time, use the following command syntax: 
    date .

The specific format is as follows:

date MMDDHHMMYYYY.SS

For example, to set the time to 1:00pm on January 1, 2007, you would type the following command:

date 010113002007.00

  1. To save the time to the hardware clock (BIOS), type the following command: 
    hwclock --systohc
  2. To ensure that the BIG-IP system daemons operate and log properly once the operating system clock has been changed, you will need to reboot the BIG-IP system. To reboot the BIG-IP system, type the following command: reboot
  3. After the system has rebooted, you can verify the system time and the hardware clock time by typing the following command at the BIG-IP command line: 
    date ; hwclock

The output appears similar to the following example: 

Thu Oct 22 17:03:16 PDT 2009
Thu Oct 22 17:03:16 2009 -0.000328 seconds
