Time Sync - Multiple Time Zones

[Guest Dragon]

Hi,

 

I have a bit strange question. I have this application that is hard coded

for a particular time zone. So the server has to be set to this time zone.

All my other servers are on local timezone. My problem is that I would like

to sync time on all my servers.

 

So if my application server is set to EST and my local timezone is PST, I

want both server to say the local time of 10AM instead of having both

servers 3 hours apart because of the time zone. So, is there any script,

batch file, utility etc that I can use to force this time sync? I also want

to make sure that I can force-sync a server even if its time is off by

months.

 

Thanks.

Re: Time Sync - Multiple Time Zones

 

The whole purpose of time synchronization is to ensure that all the

computers have the correct time regardless of where they are or what time

zone they are configured to be in. Thus, the time of day is stored

internally and synchronized as (esentially) UTC (see

http://en.wikipedia.org/wiki/UTC) and adjusted for display to humans based

on the time zone selected for the computer.

 

The only answer to your problem I can think of is to turn off the Windows

time synchronization and build yourself a custom script or application that

runs at startup and periodically thereafter that gets the (UTC) time from a

reliable source, then adjusts it to time zone you want (EST is UTC - 5

hours).

 

The net time \\computername will get the current time from another computer

and display it (human readable) adjusted for that computer's time zone and

the local computer's time zone (if they are different).

 

You will also have to take into account Daylight Savings Time changes.

It is perfectly useless to know the right answer to the wrong question.

Re: Time Sync - Multiple Time Zones

 

Thank you Bruce. I completely agree with you on this but until vendor fixes

this app, unfortunately, I am stuck with it.

 

Would you be able to provide me with some hints for a script? Here is what I

am thinking:

 

On the system with correct time (Source) schedule a batch job to run on a

regular basis. Job will create text files with date and time:

 

time /t > time.txt

date /t > date.txt

 

 

On the App server:

 

time << source\time.txt

date << source\date.txt

 

The only problem I have is "date /t > date.txt" does not give me clean date

to be used as an argument.

 

 

Am I doing it incorrectly? Any other ideas?

 

Thanks!

Don't forget that Kerberos domain authentication needs all internal clocks

to be set within 5 mins of each other

Thank you Peter. This is why I do not have that server part of the AD

structure.
