Re: SL 7.2 on a HP Zbook

[Bill Askew]

Hi Yasha
It is a Zbook 15 G2.
Ken and Mark put me on the right path.
We use our laptops unconnected to any networks.  Previous to RHEL 7 the system 
clock was saved to the hardware clock on shutdown or reboot by default. However 
NTP does sync the system and hardware clocks.  Since we do not use NTP no 
synchronization happens.

I am using SL 7.2x on a HP Zbook without this issue.  Which model?  Mine 
is several years old and thus might be different from yours.

If you grep'd the rc init files for hwclock, you will find it in halt.  You 
can't grep systemd.  All you can do is read the man page and there's a lot of 
man pages to read.  :(

Hi everyone
I am using SL 7.2 on a HP Zbook.  So far the only issue that I have is setting 
the date and time does not set the Zbook's hardware clock.  It does change the 
time for the duration of the session but when the ZBook is rebooted the time 
goes back to what it was before plus the amount of time I spent during the 
session.
Does anyone have a fix for this?

There is probably a more "systemd" type method, but this as root has always 
worked:
hwclock --systohc

The hwclock --systohc worked thanks!  :-)

Still kind of odd that the date command does not cause the date and time to the 
hardware clock when shutting down
(this is how it works on a Lenovo T61p running SL 6.2)

This is probably useful:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sect-Configuring_the_Date_and_Time-hwclock.html

There is a note about how the system clock is synced every 11 minutes to 
hardware.  This might be a configuration option in chrony or ntpd. 
Plenty of good information in that document to dig through.
