Timed loop, quick question

[Corelab]

cRio 9047, timed loop, 1MHZ timing source, 400us period. I'm looking at the Iteration Duration output of the Left Data Node (single frame loop). For this returned value, 0.0000720000, I'm not sure if I'm looking at seconds, milli, or micro. Documentations says iteration "is specified in units of the timing source". How many microseconds am I looking at?

Sorry, never mind, my timing source was 1 MHz <absolute time>, instead of 1 MHz...
