Get start time of a daq session

I'm wondering if it is possible to get the time at which the DAQ starts so that I can keep track of other code events, relative to the time the DAQ started. Currently I just keep track of the time I told the DAQ to start, but I'd prefer another method.

Edit: To clarify the meaning of "start", I mean the time at startForeground or startBackground is actually executed on the hardware. Ignoring any issues with triggering a start, what I'm really looking for is the time that input data starts OR that output data starts leaving the DAQ.

It is not clear what it means for the DAQ to "start", so I am going to guess you mean the time at which you startForeground() . If so then the answer to your question is No, that is not kept track of. The properties kept track of are noted at https://www.mathworks.com/help/daq/ref/daq.createsession.html

I see your clarification, and the answer is still NO.

Some DAQ devices have the ability to timestamp samples (at least according to the device's clock).

Yeah, that's what I figured. It won't be the end of the world for what I need. The one that still gets me a bit is, from what I can tell, the lack of an ability to get raw DAQ data (since the DAQ toolbox overhaul a couple years back)
