Synchronization and calibration of clocks for a medical device and calibrated clock

A method for synchronizing a plurality of clocks, the plurality of clocks comprising a first slave clock and a master clock, the method comprising:

• (a) comparing a first current time of the first slave clock with a second current time of a master clock, wherein the first slave clock controls a multi-modal medical device system that provides treatment therapy to a patient with a medical condition;
• (b) if the difference between the first and second current time is greater than a preset limit, determining to synchronize the first slave clock with the master clock;
• (c) in response to (b), disabling a run mode operation of the medical device system;
• (d) determining a delay time between a first time and a second time, wherein the first time includes the time for initiating the synchronization of the first slave clock and the master clock and the second time includes the time for receiving an indication to synchronize;
• (e) in response to (b), providing a reference time from the master clock;
• and
• (f) setting the first slave clock to the reference time;
• and
• (g) enabling the run mode operation of the medical device system.
