Hardware clock / software clock discrepancy on L3000
I have 2 quesitons:
1) How can I check the hardware clock's time?
2) If it is indeed off, how can I change it?
I have read some threads on the forums and there seems to be some confusion on whether the 2 clocks are supposed to synchronize each other upon boot, and if that actually always works.
Any help will be much appreciated.

Re: Hardware clock / software clock discrepancy on L3000
Perhaps I should have phrased the question a bit different. Dealing with timezone differences is a way of life here in Hawaii, so I had no difficulty in recognizing that the 5 hours difference between clocks represents precisely the lag to Eastern Standard Time from here.
Nevertheless, I still have a problem here that I do not know how to remedy. Does anyone have any suggestions?

Re: Hardware clock / software clock discrepancy on L3000
Having spent my entire UNIX Admin carier in the centeral timezone, I do not have much experience to help with this.
It will be interesting to see if someone else has a better answer for you.
Good luck,

Re: Hardware clock / software clock discrepancy on L3000
The value of TZ is set to 'HST10" which seems appropriate. However, etc/default/tz contains the value 'EST5EDT' which may be the problem. I will check with the application vendor if somehow there program picks up the date and time in a way that is not how HP-UX normally handles these things.
Thanks for the help.

Re: Hardware clock / software clock discrepancy on L3000
You need to find out what the database time zone is set to:
select dbtimezone from dual;
I suspect this is what was called the 'hardware' clock.
You can change the timezone for a session like this:
ALTER SESSION SET TIME_ZONE = '-10:00';
You can also set the session TZ using environment variables as well. I suggest you search Oracle's Metalink where you should find ton's of data on timezones.
