If the utilized archive type is none cyclic and this property is
set to 0, then all archive entries between the start- and the end
time will be returned.
Otherwise (i.e. "Raster" property set greater than 0 and the
archive type is cyclic) not all archive entries will be returned,
but beginning with the start time each N-th (N="Raster") entry is
returned.
Example:
Cyclic archive with an cylic rate of 15 minutes (900 seconds) →
Entries are recorded every 15 minutes (e.g. 07:45, 08:00, 08:15,
...)
"StartTime" is 12:15 and the "Raster" property is set to 3 → Every
third entry is returned (e.g. 12:15, 13:00, 13:45, 14:30, ...)
ATTENTION: If the start time doesn't match the archive cyle
time then no data entries will be returned.
e.g. Archive entries are 12:15, 12:30, 12:45, 13:00, ...
"Raster" is set to 3, but "Start-Time" is set to 12:16 → It would
return 12:16, 13:01, 13:46 but archive cycle is lagging one minute
behind → No entries will be returned!
