Synchronizing time-of-day (TOD) between TOD components includes issuing an order for a plurality of TOD components, each including a local time, an offset, and an effective time as a sum of the local time and the offset. The effective time of a reference TOD component is the reference time to which target TOD component(s) are to be synchronized.
