[Discuss-gnuradio] VRT-branch bug?

[Per Zetterberg]

Dear UHD developers and all,

I hope you don't stop reading this because it's about the obsolete 
VRT-branch. It may apply to UHD as well.

Everything I have tried with the VRT-branch has worked until today. 
This is nice because I have been looking for the "transmit at time t" 
functionality for many years.

I can perfectly synchronize the transmitter and receiver by setting: 
"hdr.integer_secs=10; hdr.fractional_secs=0" in transmitter and 
"t.secs=10; t.ticks=0" in the receiver. If I change to t.ticks=400, in 
the receiver the received signal is shifted as it is supposed to. 
However, if I set "hdr.fractional_secs=100" or anything else nothing 
happens. It seems as if the ".fractional_secs" field is ignored.
