Keeping time up to date on the vRealize Automation appliances

In my lab I’ve had some issues with my vRealize Automation (vRA) / vCloud Automation Center (vCAC) appliances not having the correct time even though time was configured in the appliance admin pages.  I was able to get the time to be consistently correct by creating a cron job on each of the appliances.  Here is the process for creating a cron entry to sync the appliance’s time with an external time server.

1) ssh or open a console to the appliance.  Login as root.

2) Open the crontab for root: crontab -e

When you run the crontab command on the appliances it launches the VI editor.  If you need more info on VI, you can search for it.  Here is a cheatsheet: http://www.albany.edu/faculty/hy973732/ist535/vi_editor_commands.pdf

3) Enter insert mode by entering a lower case i

4) Paste in the following or add to the existing entries:

# ------------- minute (0 - 59)
 # | ----------- hour (0 - 23)
 # | | --------- day of month (1 - 31)
 # | | | ------- month (1 - 12)
 # | | | | ----- day of week (0 - 6) (Sunday=0)
 # | | | | |
 */5 * * * * /usr/sbin/sntp -P no -r 192.168.1.254

5) Save the file by pressing escape :wq <enter> or escape ZZ

*/5 means to update the time every 5 minutes and 192.168.1.254 is my time server.
