I have a C++ implemented flow-graph that acquires 3 channels at a sample
rate of 5 MHz. There are a couple of decimation stages with the resultant
n a number of 250 Hz output channels. How is the best way to access the
associated time stamps. I wouldn't need every time stamp, just perhaps one
ev
USRPs will only output timestamps at the beginning of streaming, or when
time skips (e.g. after an overrun). You can keep track of time by
counting samples in between timestamp tags.
See the header_payload_demux block for an example of how to keep track
of time. Also, check out the gr-uhd manual f
As of v3.7.10 there is a command port handler for forcing a new time tag.

It's not strictly necessary since you can always count time yourself, but
it can be useful for some things.

Thank you Martin.
This one looks like it will involve some research. If I have time I'll
pursue it. In the meantime if anyone has some C++ example code that
shows how an application might extract time tags, I would be grateful.
