 //		Olt Vendor Id
-//			OLT vendor ID: This attribute identifies the OLT vendor. It is the same as the four most

-//			Equipment ID: This attribute may be used to identify the specific type of OLT. The default value

 //		Version
-//			Version:	This attribute identifies the version of the OLT as defined by the vendor. The default

 //		Time Of Day Information
+//			This attribute provides the information required to achieve time of day synchronization between
+//			a reference clock at the OLT and a local clock at the ONU. This attribute comprises two fields:
+//			the first field (4-bytes) is the sequence number of the specified GEM superframe. The second
+//			field (10-bytes) is TstampN as defined in clause 10.4.6 of [ITUT G.984.3], clause 13.2 of [ITUT
+//			G.987.3] and clause 13.2 of [ITU-T G.989.3], using the timestamp format of clause 5.3.3 of [IEEE
+//			1588]. The value 0 in all bytes is reserved as a null value. (R,-W) (optional) (14-bytes)
+//
 //			NOTE - In ITU-T G.987/ITU-T G.989 systems, the superframe count field of the time of day
 //			information attribute contains the 32 LSBs of the actual counter.
