UDS 4.0 - Time Zone issue

38 Views

Hi,

1.MII Server is in GMT timezone

2.UDS Server is in CST Timezone

3.Historian is in CST TimeZone.

I have used the Tag Query to get the Data from Historian from 2009-Aug-01 6:00 to 2009-Aug-01 7:00. And the results are like this

DateTime TagValue

2009-Aug-01 06:00:00 123.32

2009-Aug-01 06:00:01 153.21

2009-Aug-01 06:02:00 234.12

.......

..........

............

But when i compared this data with the actual data i received from Plant engineers, i found that this is actually the data from 2009-Aug-01 1:00 to 2009-Aug-01 2:00 on Historian(which is in CST timezone).

My question is: As i am not passing the TimeZone in the Start and End Dates in Tag Query, i should actually get the data from 06:00 to 07:00(CST) instead of 01:00 to 02:00(CST)

Am i wrong with this assumption?.

Thanks,
