Retrieve tags with 1ms time difference

Hello all,

 

I am extracting data into excel from 'Tag1' using datalink by using PICompData.  I am then getting the value of several other tags by using PIArcVal for each timestamp generated.

 

Each of these tags always has data generated at the same time, and are scanned at 1 second intervals, however occasionally I don't get a value returned for the other tags.

 

Having looked into it further, it appears that occasionally the other tags have a timestamp that is offset by +/- 1 ms.

 

Is there an obvious solution to this issue, where I can get data without being affected by this micro time offset?
