DescriptionThis article explains how to configure the date and time of a Shelf Manager. It includes the timezone and NTP configuration.
ScopeAll Shelf Managers.
SolutionThere are 2 ways to configure the time on the Shelf Manager.
1. The first solution is to set the date and time manually with the command below:
# date 03141636002016
Mon Mar 14 16:36:00 CET 2016
To make it persistent (The Shelf Manager must have a battery, otherwise the configuration will be lost at the next reboot):
# hwclock --systohc
2. The second solution is to obtain the time from a NTP server. This is the preferred solution.
a) Reboot and break the boot sequence:
# reboot
The system is going down NOW !!
Sending SIGTERM to all processes.

b) Modify variables as follows (in EST timezone):
setenv timezone EST5
setenv time_server 10.5.0.3
setenv time_proto ntp
Note : EST is the timezone, 5 is the offset. The offset specifies the time value that must be added to the local time to get a Coordinated Universal Time value.
To specify CET timezone, set:
setenv timezone CET-1
c) Save the variables and reboot to the main partition :
shmm500 saveenv
Saving Environment to EEPROM...
shmm500 reset
d) At the boot, the Shelf Manager tries to sync with the NTP server:
/etc/netconfig: Starting time synchronization with 10.5.0.3
Looking for host 10.5.0.3 and service ntp
e) Verify the time:
# date
Mon Mar 14 10:53:06 EST 2016
If the time is incorrect, either wait 5 minutes for the next NTP sync attempt or force NTP sync using the command:
# ntpdate -u -s 10.5.0.3
Looking for host 10.5.0.3 and service ntp
host found : 10.5.0.3
Optionally, modify the NTP sync interval (default is 300 seconds). Modify 'INTERVAL' value in /etc/timesync
