A representation of the relative occurrence of the ALARM/EVENT. The contents of the octets in this OBJECT are actually the ONEs COMPLEMENT of the values represented, a neccessity due to the fact that umc1CurAlmTable entries must be retrievable in reverse chronological order as the table is walked. This would result in decrementing column index values as the umc1CurAlmOccurrenceIndex column was traversed. The true occurrence values can be extracted from this octet string by taking the COMPLEMENT of each byte (with the exception of octets 0 and 1, which must first be combined into a 16 bit representation of the year before COMPLEMENTing and then broken apart into the High and Low bytes after the COMPLEMENT has been accomplished). The format of the umc1CurAlmOccurrenceIndex is as follows: octet[0] High 8bits of the YEAR octet[1] Low 8bits of the YEAR octet[2] Month (January is 1, February is 2, etc.) octet[3] Day (1 through 31) octet[4] Hour (0 through 23) octet[5] Minutes (0 through 59) octet[6] Seconds (0 through 59) octet[7] mSec (0 through 255). This is an index to differentiate this alarm from any others that may have occurred in the same second.
