fixedWindowRollup of less than 1 second

This might be a lack of knowledge on my part but I can't seem to see a way to specify a time period of under 1 second for a TimeSeries.fixedWindowRollup. Is this possible?

Cheers,

Start at the TimeSeries.fixedWindowRollup entry point and trace how its time period is represented. Check the existing rollup behavior for sub-second values and establish whether the expected result is support for such windows or a clear explanation of the limitation.
