Thanks alot...Lot of information you gave me....
Question...Whats the appropirate proceedure on a dual-boot Windows/UNIX
system time settings??
1. Do i need to set the CMOS clock to UTC and the actual OS or diplayed
time would be LOCAL TIME according to my local Time Zone?
2. Next question...what time proceedures do all the Government systems
use as far as them running UNIX machines? Do they have the RTC clock
set to UTC and the OS displayed time as local time? Or, do they run
both as UTC??
3. Last question - Someone told me to make life so much easier for UNIX
system admins is to have their UNIX servers run UTC. In general, in a
production environment like a data centre, it is better to keep all
servers in UTC (or Zulu) time. Then ensure that all front-end
applications manage the display of the time depending on where the
disply is appearing. It will make your your life SOOOOO much easier.
But does that actually mean to have the servers have their RTC clock
set to UTC and the applications logs are dispplayed in local times??
What does this actually mean in # 3 ??
Thanks
Please advise...

I am running a UNIX
operating system on a PC and I did set my CMOS or the Hardware Clock to
use the system time as UTC while the operating system clock or the
DISPLAYED TIME is set to local time adjusted from the CMOS clock in the
BIOS which is in UTC.
So I would like to ask everyone out here as to which is the best amd
more preferrable time or clock settings to use on UNIX systems?
1. Should I leave the RTC or Hardware Clock as UTC and set the
DISPLAYED TIME as LOCAL TIME?
2. Or, set the DISPLAYED TIME as UTC time also while keeping the
Internal or CMOS clock as UTC too?
I was told one time, that in large corporate datacenters that use UNIX,
there kept in UTC. But are they referring to the Internal Clock, or the
actual operating system clock?
I would greatly appreciate the help in advance. This is very important
to me.
