Id (1 byte): An 8-bit unsigned integer that MUST contain the value 0x01.
Length (1 byte): An 8-bit unsigned integer that specifies the length, in bytes, of the PDU. This field MUST be set to 0x12.
PromptForCredentialsMillis (4 bytes): A 32-bit unsigned integer that specifies the difference, in milliseconds, between the time when the connection was initiated, and the time when a credentials prompt dialog was shown to the user. This value MUST be zero if no credentials prompt dialog was displayed.
PromptForCredentialsDoneMillis (4 bytes): A 32-bit unsigned integer that specifies the difference, in milliseconds, between the time when the connection was initiated, and the time when credentials were successfully provided by the user. This value MUST be zero if no credentials prompt dialog was displayed.
GraphicsChannelOpenedMillis (4 bytes): A 32-bit unsigned integer that specifies the difference, in milliseconds, between the time when the connection was initiated, and the time when the Remote Desktop Protocol: Graphics Pipeline Extension dynamic virtual channel ([MS-RDPEGFX] section 2.1) was accepted by the client.
FirstGraphicsReceivedMillis (4 bytes): A 32-bit unsigned integer that specifies the difference in milliseconds, between the time when the connection was initiated, and the time when the first Desktop Protocol: Graphics Pipeline Extension graphics message ([MS-RDPEGFX] section 2.2) was received by the client.
