That should not be a problem as there is one statement that strips the seconds from the start timestamp found in the first data line. Can you identify and correct it to your needs?


If you supply the start time from the outside, the problem should not exist.


Be aware that in the sample data you supplied 5 lines would NOT print if you define the start time as 09:55:39 (that's the reason I stripped the seconds, BTW).

GR_PLOT_INT(1)							   User Commands						    GR_PLOT_INT(1)

NAME
gr_plot_int.py - plot integer binary data using GNU Radio SYNOPSIS
gr_plot_int: [options] input_filenames DESCRIPTION
Takes a GNU Radio integer binary file and displays the samples versus time. You can set the block size to specify how many points to read in at a time and the start position in the file. By default, the system assumes a sample rate of 1, so in time, each sample is plotted ver- sus the sample number. To set a true time axis, set the sample rate (-R or --sample-rate) to the sample rate used when capturing the sam- ples. OPTIONS
-h, --help show this help message and exit -B BLOCK, --block=BLOCK Specify the block size [default=1000] -s START, --start=START Specify where to start in the file [default=0] -R SAMPLE_RATE, --sample-rate=SAMPLE_RATE Set the sampler rate of the data [default=1.0] SEE ALSO
