ArchiveFilter.Raster

ArchiveFilter.Raster

Hello!
How do you use "Raster" property of the ArchiveFilter?
I tried the following:
ArchiveFilter.Raster=some value
ArchiveFilter.StartTime=Start
ArchiveFilter.EndTime=End
Set zArvVars=ArchiveFilter.Query
NumberOfValues = zArvVars.Item(0).ArchiveValues.Count
but the number of values I get is always the same either "Raster" property is 0 or >0.
The archive is cyclic archive with scan time 15 min and the start time of the filter is synchronized with archive scan cycle (e.g. start time at 12:15:00).
Does the "Raster" property >0 shorten query time?
Is there a way to query archive (in VBA) at exact time points (like in SQL statement) not using "Raster" property?
Best regards,
Gregor
