Email from Alex:

Turned out to be the lack of current year information in the IRIG-B signal
received by the Symmetricom GPS card in the frame builder machine caused
this. I have added a constant in daqdrc to bring the seconds forward:

controls@fb /opt/rtcds/caltech/c1/target/
fb $ grep symm daqdrc
#set symm_gps_offset=-1;
set symm_gps_offset=31536001;

Hopefully we will be upgrading to the newer timing system at the 40M this
year, so this will not happen again next year.


 

Doing an 'ls -lrt' in /frames/full/ now shows that the names are correct:
