ResolutionBy default the Aveksa sourced appliance uses the rdate command to synchronize the time on the system. Also by default ACM attempts to connect to a public time service - however most sites block both rdate and access to public time servers. To change the time synchronization method use the following:
To use rdate ask the client what their internal time server is and enter it in the UI.
You should test it (as root) from the command line
 
rdate <host>

If the rdate command does not work, you can try using the ntpdate command with this syntax (use the same host as above and also do it as root)
 
ntpdate -s <host>

or
ntpdate -s -u <host>

If ntpdate works you can create / modify the updatetime script in /etc/cron.daily to sync the time on the appliance. The script consists of the line you used to get the time from the server.
