摘要:
A slave device includes: a clock unit that outputs time information; a message receiving unit that receives messages sent from a master device; a message sending unit that sends messages to the master device; a calculation unit that calculates a correction value necessary for correcting the time on the clock unit; and a correction unit that corrects the time on the clock unit based on the correction value calculated by the calculation unit.
