# Test time
Test time starts at 0.00202233736299 s (2022.34 microseconds)
Test time ends at 0.00209009036032 s (2090.09 microseconds)
Therefore, total test time is 6.77529973229e-05 s (67.75 microseconds)
This is from 78.10 - 145.86 microseconds after flow arrival.
------------------------------------------------------------
trigbox arrival at 0.0019998 s (1999.80 microseconds).
This is 55.57 microseconds after flow arrival.
