StartTime  

Description 

(Read-only) Returns the time the server started running.  This is the start time of the server that the 

client has specified to connect to.  Multiple Clients connecting to the same server can be assured 

that each client will read the same value from the server for this property. 

Syntax 

StartTime As Date 

Remarks 

The automation server is expected to use the custom interface GetStatus () to obtain the values for 

this property as well as many of the other properties defined as properties of the OPCServer. An 

error occurs if the client has not connected to a Data Access Server via the Connect method.
