LHCb:MuSyC: a Software Package for the time alignment of the LHCb Muon System

The LHCb Muon System consists of 122000 front-end channels, which require being time-aligned within about 2 ns for proper operation of the experiment trigger. We describe a program which, on the base of the information acquired directly from detector, is able to calculate all the time parameters (programmable delay settings) to be loaded at different stages of the System in order to fix the necessary system calibration. The same criteria and similar procedures are also used to monitor the correct system time behavior during data-taking.
