What Time Zone to use for a change

Our data center is in EST. We have another data center in CST. We will be moving the mainframes from data center in CST to the one in EST. Currently both data centers use the same change management tool, but the implementation time is based on where the change was being made.

Now, with the mainframes moving from CST to EST, they will continue to run the clock on the systems in CST. The question then comes up for changes to be implemented for the systems that moved. What time zone do we use on the changes for these systems that moved? Do we use CST, since they will be running the clock as if they were still in CST or do we use EST, because the mainframes are physically located in EST?

Thanks.

I am a rule would use ZULU Time or GMT if you have sites/data centers around the world or in multiple data centers

As ZULU Time or GMT never changes, this is a good thing

The only issue is that you will most likely have to translate the time for each report

The other issue is whether the rest of the company is that timezone smart

ITIL does not say anything. This is merely a company policy that would be set

Hello, my company has offices all across the US too. I'm going to ask the US Change Manager how he handles it and let you know...

Hi,

GMT or UTC (very similar) if you have a global presence. You should also have the capability to show the time in the different time zones for those locations via your change management tool.

For reporting changes on a global report I find GMT / UCT to be best as people can calaulate from that easier.

GMT always - as we (the Brits!) created Time, so it is the one to use.

Oh for the days of imperial coloniolism again... *sigh* Wink

wrong wrong wrong

time was invented so that everything did not appear at once

space was invented so that when it should up, there would be room for it

delivery service was invented so that it would be sent to the wrong house first

gmt came about because that damn fool clock maker was the first one to successfully track longitude using a time piece. harrison or something like that

as i live in greenwich, uk i will have to go to it

wo wo wo.... Harrison the "damn fool who invented the clock"???

I am sure that Harrison was way smarter than the guys who invented ITIL!!!

Oh, for the time, my entire company is in one timezone, so we don't have any problems with it - we just use local time.
