affect pause triggers. Pause triggers are considered to be configured
for all sessions if either one or the other of the following conditions
is true: - No session has a pause trigger that is None - One session has
a pause trigger that is None and all other sessions have pause triggers
other than None. The one session with the None trigger must have
pause_trigger_master_session set to itself, indicating
that the session itself is the pause trigger master Note: TClk
synchronization is not supported for pause triggers on acquisition
sessions.

min_time (float in seconds or datetime.timedelta): Minimal period of TClk, expressed in seconds. Supported values are
between 0.0 s and 0.050 s (50 ms). Minimal period for a single
chassis/PC is 200 ns. If the specified value is less than 200 ns,
NI-TClk automatically coerces minTime to 200 ns. For multichassis
synchronization, adjust this value to account for propagation delays
through the various devices and cables.
