i have a data source which i'm looking to set update on a per second interval.
but i would like to log data every 15 mins.
when producing reports, is it possible to get the 15 min interval quantize, i.e. 0min, 15 min, 30 min, 45 min etc etc.
i have managed to get 1 sec polling with 15 min interval logging ok, but i really need to have it on the times stated, not 15 min elapsed.
for now i've changed the data source polling to every 15 mins and logging to when time stamp changes, but this is not really practical.
live readings need to be update more frequently.
