Communication apparatus, control method therefor, and storage medium

A control method for a communication apparatus including a plurality of communication control units each including a hardware clock, the control method comprising:

• determining an adjustment parameter value to adjust a time of the hardware clock in a first communication control unit of the plurality of communication control units, based on a precision time protocol (PTP), the first communication control unit being configured to communicate with a time distribution server;
• adjusting, as a first adjustment, the time of the hardware clock in the first communication control unit using the adjustment parameter value;
• and
• adjusting, as a second adjustment, a time of the hardware clock in at least one second communication control unit using the adjustment parameter value, the second communication control unit being included in the plurality of communication control units and being different from the first communication control unit.

A non-transitory storage medium storing a program causing a communication apparatus including a plurality of communication control units each including a hardware clock to execute a control method, the control method comprising:

• determining an adjustment parameter value to adjust a time of the hardware clock in a first communication control unit of the plurality of communication control units, based on a precision time protocol (PTP), the first communication control unit being configured to communicate with a time distribution server;
• adjusting, as a first adjustment, the time of the hardware clock in the first communication control unit using the adjustment parameter value;
• and
• adjusting, as a second adjustment, a time of the hardware clock in at least one second communication control unit using the adjustment parameter value, the second communication control unit being included in the plurality of communication control units and being different from the first communication control unit.
