Hello,
I would like to understand the Duration Good calculation provided for the below interval against all sets of Historian input data.
Basically why the additional 1 milli second included in this partial interval?
| 12:01:20.000 | 7001 | Good, Calculated, Partial |
Thanks & Regards

Samba,
It includes the tick at the end. i.e. 12:01:20.000 - 12:01:36.000 interval, the actual data good data is 12:01:23.000 - 12:01:30. - if you just subtract you get 7000 milliseconds, but that would not include the last milli-second - which you know still had a good value, thus 1 milli-second more.

Paul,
If I am not wrong we are talking about the following data from hostorian 2
12:01:23 70 Raw, Good
12:01:26 80 Raw, Good
12:01:30 90 Raw, Good
after which we don't have any data available. So which is the last milli second you are pointing out in this data which has a good value?

Saurabh,
Yes the last value is 12:01:30.000 which is 1 more milli-second then just the subtract of the two times (which would be the time between them) but the last new value is present for a single milli-second
