Issue

Figure F.9 shows an incorrect encoding for BINARY-TIME and could let believe that IEC 61850 uses the C37.118 representation

Proposal

Modify Figure F.9

CHOICE {…binary-time [12] IMPLICIT BINARY TIME <DD DD MS MS MS MS>}, -- TimeOfEntry
should be
CHOICE {…binary-time [12] IMPLICIT BINARY TIME <MS MS MS MS DD DD>}, -- timeOfEntry

CHOICE {... utc-time [17] IMPLICIT UtcTime<SS SS SS SS QQ MM MM MM>}, -- t
should be
CHOICE {... utc-time [17] IMPLICIT UtcTime<SS SS SS SS MM MM MM QQ>}, -- t
(it should be better Btime6 since BINARY-TIME is a variant)

The proposal is correct except for lower case at timeOfEntry. TimeOfEntry not timeOfEntry.

BINARY TIME over the wire is MS MS MS MS DD DD
UtcTime over the wire is SS SS SS SS MM MM MM QQ

CHOICE {…binary-time [12] IMPLICIT BINARY TIME <DD DD MS MS MS MS>}, -- TimeOfEntry
should be
CHOICE {…binary-time [12] IMPLICIT BINARY TIME <MS MS MS MS DD DD>}, -- TimeOfEntry

CHOICE {... utc-time [17] IMPLICIT UtcTime<SS SS SS SS QQ MM MM MM>}, -- t
should be
CHOICE {... utc-time [17] IMPLICIT UtcTime<SS SS SS SS MM MM MM QQ>}, -- t
