The RSA Identity Governance & Lifecycle hardware appliance is already configured to synchronize its system clock with a public time server, clock.psu.edu. This RSA Knowledge Base Article explains some commands to manually define the date and time on a hardware appliance.
Login to the appliance as the root user:
Set the timezone (if other than the default EST)
Navigate to /usr/share/zoneinfo.
Find your timezone.
Backup the original timezone file.
cp /etc/localtime /etc/localtime.old
Copy the new timezone
cp <newtimezone> /etc/localtime
Set date and time:
date -s "30 APR 2009 14:03:00"
Sync the BIOS hardware clock
To synchronize the appliance to a corporate timeserver or an NTP server, please see the following RSA Knowledge Base Articles:
