1440 Time synch for client

Clause: Table 107
Category: Issue for edition 2 of this part
It's not clear if an MMS client shall support time synch or not. Is it Mandatory, Optional or Conditional? TISSUE #820 (annex) states time synch is optional for MMS clients. Table 107 states time synch shall be implemented together with at least one other application profile. During the UCAiug Telco it was proposed to change it to conditional: "in case the client supports Operate". But is it mandatory that the Operate request shall contain a valid timestamp? People can think of an application that will check the timestamp & timestamp quality of the Operate request. Other applications don't care. So it seems be "application dependent" just like for example to use GOOSE or not for certain applications and end-users need to specify it in their specification that the MMS client shall support time synch when needed.
Confirm that time synch for MMS clients is optional or clarify it's conditional with the condition.
