Tried both re-configuring and rebooting the dbbc but to no avail. The fmset values were also in sync until around 1100UT (when the mark 5B clock was ahead by 0.2). Did an fmset sync at this stage which fixed the issue. The scans from 004-1026 to 004-1044 were probably affected due to the high clkoff value. The schedule was halted from 004-1046 to the 004-1053a (Prad). 1343UT-The ckloff value dropped to the order of E-001.
