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,
Gowtham K.
